Page Title 11. Sapna went to the stationers and bought things worth Rs 25, out of which 30 paise went to sales tax on taxable purchases. If the tax rate was 6%, what was the cost of the tax free items?
Rs. 15
Rs. 19.70
Rs. 23
Rs. 20.70
Answer: option B

Let the amount taxable purchases be Rs. X.

Then, 6% of X = 30/100

⟹ X = (30/100 x 100/6) = 5

∵ Cost of tax free items = Rs. [25 - (5 + 0.30)] = Rs. 19.70



12. The population of a town increased from 1,75,000 to 2,62,500 in a decade. The average percentage increase of population per year is:
15%
10%
8%
5%
Answer: option D

Increase in 10 years = (262500 - 175000) = 87500.

Increase% = (87500/175000 x 100)% = 50%

∵ Required average = (50/10)% = 5%



13. Bhushan buys goods worth Rs. 6650. He gets a discount of 6% on it. After getting the discount he pays sales tax at the rate of 10%. Find the amount to be paid to him for the goods.
Rs. 6876.10
Rs. 6830
Rs. 7600.10
Rs. 5576
Answer: option A

discount = 6% of Rs. 6650 = Rs.(6/100 x 6650) = Rs. 399

Sales tax = 10% of Rs. (6650 - 399) = Rs.(10/100 6251) = Rs. 625.10

∵ Final amount = Rs. (6251 + 625.10) = Rs. 6876.10



14. Two tailors X and Y are paid a total of Rs. 550 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?
Rs. 230
Rs. 270
Rs. 250
Rs. 200
Answer: option C

Let the sum paid to Y per week be Rs. Z.

Then, Z + 120% of Z = 550.

⟹ Z + (120/100)Z = 550

⟹ (11/5)Z = 550

⟹ Z = (550 x 5 /11) = 250.
