Q. 1  (a)     Calculate Ushr on a rice crop by natural resources amounting to Rs.9,30,000.                                                                           (10)

         (b)     Calculate Zakat on gold amounting to Rs.13,50,000.             (10)

 

(a) To calculate Ushr on a rice crop, the Ushr rate needs to be determined. The Ushr rate for agricultural produce varies based on factors such as the type of crop and the region. Let's assume the Ushr rate for rice crop in this scenario is 10%.

 

Ushr amount = (Total crop value) x (Ushr rate)

 

Given that the natural resources amount to Rs. 9,30,000:

 

Ushr amount = Rs. 9,30,000 x 0.10

Ushr amount = Rs. 93,000

 

Therefore, the Ushr on the rice crop by natural resources amounts to Rs. 93,000.

 

(b) To calculate Zakat on gold, the Zakat rate for gold needs to be determined. The Zakat rate for gold is typically 2.5%.

 

Zakat amount = (Total gold value) x (Zakat rate)

 

Given that the gold amount is Rs. 13,50,000:

 

Zakat amount = Rs. 13,50,000 x 0.025

Zakat amount = Rs. 33,750

 

Therefore, the Zakat on gold amounting to Rs. 13,50,000 is Rs. 33,750.

Q. 2   (a)     If the stay of 12 men for 7 days in a hotel cost Rs.20,500. Find the cost for the stay of 10 men for 8 days.                                    (10)

         (b)     Two angles in a triangle are 45o and 75o. Find the ratio of the third angle to the sum of the first two angles.                        (10)

 

(a) To find the cost for the stay of 10 men for 8 days, we can use the concept of proportionality.

 

Let's assume the cost for the stay of 10 men for 8 days is C.

 

According to the given information, the cost for the stay of 12 men for 7 days is Rs. 20,500.

 

We can set up a proportion based on the number of men and the number of days:

 

12 men / 7 days = 10 men / 8 days

 

Cross-multiplying, we get:

 

12 men * 8 days = 10 men * 7 days

 

96 men-days = 70 men-days

 

Now, we can calculate the cost for the stay of 10 men for 8 days:

 

C = (Cost for 12 men for 7 days * 70 men-days) / 96 men-days

 

C = (Rs. 20,500 * 70) / 96

C = Rs. 14,979.17 (approx.)

 

Therefore, the cost for the stay of 10 men for 8 days is approximately Rs. 14,979.17.

 

(b) The sum of the angles in a triangle is always 180 degrees.

 

Let's assume the third angle in the triangle is A.

 

Given that two angles in the triangle are 45 degrees and 75 degrees:

 

Third angle = 180 degrees - (45 degrees + 75 degrees)

Third angle = 180 degrees - 120 degrees

Third angle = 60 degrees

 

Now, we can find the ratio of the third angle to the sum of the first two angles:

 

Ratio = Third angle / (Sum of first two angles)

Ratio = 60 degrees / (45 degrees + 75 degrees)

Ratio = 60 degrees / 120 degrees

Ratio = 0.5

 

Therefore, the ratio of the third angle to the sum of the first two angles is 0.5.

 

 

Q. 3   (a)     The marked price of a wall clock is Rs.900. The shopkeeper offers a discount of 5% and still gains 10%. Find the price at which the shopkeeper purchased it.                                       (10)

         (b)     Divide Rs.18,400 in three friends such that the ratio of their parts is 3:6:8.                                                                                      (10)

 

(a) To find the price at which the shopkeeper purchased the wall clock, we can use the concept of successive discounts and gains.

 

Let's assume the cost price of the wall clock is C.

 

Given that the marked price of the wall clock is Rs. 900 and the shopkeeper offers a discount of 5%. This means the shopkeeper sells the wall clock for 95% of the marked price.

 

First discount price = (95% of the marked price) = 0.95 * Rs. 900 = Rs. 855

 

Now, we are told that the shopkeeper still gains 10%. This means the selling price is 110% of the cost price.

 

Selling price = (110% of the cost price) = 1.10 * C

 

Since the shopkeeper sells the wall clock for Rs. 855, we can equate the selling price to Rs. 855:

 

1.10 * C = Rs. 855

 

Now, we can solve for C:

 

C = Rs. 855 / 1.10

C ≈ Rs. 777.27 (approx.)

 

Therefore, the price at which the shopkeeper purchased the wall clock is approximately Rs. 777.27.

 

(b) To divide Rs. 18,400 among three friends in the ratio of 3:6:8, we need to determine the parts allocated to each friend.

 

The total ratio is 3 + 6 + 8 = 17.

 

Let's assume the common ratio factor is x.

 

The parts allocated to each friend can be calculated as follows:

 

Friend 1: (3/17) * Rs. 18,400 = Rs. (3/17) * 18,400 = Rs. 3,200

Friend 2: (6/17) * Rs. 18,400 = Rs. (6/17) * 18,400 = Rs. 6,400

Friend 3: (8/17) * Rs. 18,400 = Rs. (8/17) * 18,400 = Rs. 8,800

 

Therefore, the parts allocated to the three friends in the ratio of 3:6:8 are Rs. 3,200, Rs. 6,400, and Rs. 8,800, respectively.

 

 

Q. 4   (a)     At what annual rate of profit would a sum of Rs.780 will increase to Rs.1340 in 2 years 3 months?                                                   (10)

         (b)     Find the compound profit on Rs.3000 for 2years at 4%.    (10)

 

(a) To calculate the annual rate of profit, we can use the formula for compound interest:

 

Amount = Principal * (1 + Rate/100)^Time

 

Given that a sum of Rs. 780 increases to Rs. 1340 in 2 years 3 months (or 2.25 years), we can calculate the annual rate of profit.

 

Principal = Rs. 780

Amount = Rs. 1340

Time = 2.25 years

 

Using the compound interest formula, we have:

 

Rs. 1340 = Rs. 780 * (1 + Rate/100)^2.25

 

Dividing both sides of the equation by Rs. 780:

 

(1340/780) = (1 + Rate/100)^2.25

 

Taking the square root of both sides:

 

sqrt(1340/780) = 1 + Rate/100

 

Calculating the square root and simplifying:

 

1.0838 ≈ 1 + Rate/100

 

Subtracting 1 from both sides:

 

0.0838 ≈ Rate/100

 

Rate ≈ 8.38%

 

Therefore, the annual rate of profit would be approximately 8.38%.

 

(b) To calculate the compound interest on Rs. 3000 for 2 years at 4%, we can use the compound interest formula:

 

Compound Interest = Principal * [(1 + Rate/100)^Time - 1]

 

Principal = Rs. 3000

Rate = 4%

Time = 2 years

 

Using the compound interest formula, we have:

 

Compound Interest = Rs. 3000 * [(1 + 4/100)^2 - 1]

Compound Interest = Rs. 3000 * [(1.04)^2 - 1]

Compound Interest = Rs. 3000 * [1.0816 - 1]

Compound Interest = Rs. 3000 * 0.0816

Compound Interest ≈ Rs. 244.80

 

Therefore, the compound interest on Rs. 3000 for 2 years at 4% is approximately Rs. 244.80.

 

 

Q. 5   (a)     The price of a motorcycle is Rs.4000. If 9% sales tax is charged, then calculate the amount of sales tax on 25 such motorcycles.                                                                          (10)

            (b)        If gross pay of a person is Rs.650,000, then calculate his net take home salary, after deductions of Rs.380 as income tax, Rs.700 as benevolent fund, Rs.2100 as G.P fund and Rs.250 as group insurance.            (10)

 

(a) To calculate the amount of sales tax on 25 motorcycles, we first need to find the sales tax for one motorcycle and then multiply it by 25.

 

Given that the price of one motorcycle is Rs. 4000 and the sales tax rate is 9%:

 

Sales tax for one motorcycle = 9% of Rs. 4000

Sales tax for one motorcycle = (9/100) * Rs. 4000

Sales tax for one motorcycle = Rs. 360

 

Now, to calculate the sales tax on 25 motorcycles, we multiply the sales tax for one motorcycle by 25:

 

Sales tax on 25 motorcycles = Rs. 360 * 25

Sales tax on 25 motorcycles = Rs. 9,000

 

Therefore, the amount of sales tax on 25 motorcycles would be Rs. 9,000.

 

(b) To calculate the net take-home salary after deductions, we subtract the deductions from the gross pay.

 

Given:

Gross pay = Rs. 650,000

Income tax deduction = Rs. 380

Benevolent fund deduction = Rs. 700

G.P. fund deduction = Rs. 2100

Group insurance deduction = Rs. 250

 

Net take-home salary = Gross pay - (Income tax + Benevolent fund + G.P. fund + Group insurance)

 

Net take-home salary = Rs. 650,000 - (Rs. 380 + Rs. 700 + Rs. 2100 + Rs. 250)

Net take-home salary = Rs. 650,000 - Rs. 3430

Net take-home salary = Rs. 646,570

 

Therefore, the net take-home salary, after deductions, would be Rs. 646,570.
