Question 6
Easy
A store has an offer 'Buy 4 Get 1 Free'. What is the net percentage of discount ?
A 16.67%
B 20%
C 22.5%
D 25%
Correct Answer: B

Explanation:

Under 'Buy 4 Get 1 Free', the customer receives a total of 4 + 1 = 5 articles, out of which 1 article is free. Discount percentage = [Free articles / Total articles] * 100 = (1 / 5) * 100 = 20%.
Question 7
Medium
The total discount on Rs.1860 due after a certain time at 5% is Rs. 60. Find the time after which it is due -
A 6 months
B 8 months
C 10 months
D 1 year
Correct Answer: B

Explanation:

Amount = Rs. 1860, TD = Rs. 60. PW = 1860 - 60 = Rs. 1800. Rate R = 5% p.a. Time T = (100 × TD) / (PW × R) = (100 × 60) / (1800 × 5) = 6000 / 9000 = 2/3 year. In months = (2/3) × 12 = 8 months.
Question 8
Easy
A single discount equivalent to the successive discounts of 10%, 20% and 25% is = ?
A 44%
B 46%
C 48%
D 50%
Correct Answer: B

Explanation:

Effective multiplier = (1 - 0.10) * (1 - 0.20) * (1 - 0.25) = 0.90 * 0.80 * 0.75 = 0.72 * 0.75 = 0.54. Net discount = (1 - 0.54) * 100 = 46%.
Question 9
Medium
The marked price of an article is Rs. 550. A shopkeeper allows a discount of 20% and still gets a profit of 10%. If he sells it for Rs. 470, his profit percent will be:
A 15%
B 16.5%
C 17.5%
D 18%
Correct Answer: C

Explanation:

SP1 = 550 × 0.80 = Rs. 440. Profit is 10%, so 1.10 × CP = 440 => CP = 440 / 1.10 = Rs. 400. If sold for SP2 = Rs. 470, profit = 470 - 400 = Rs. 70. Profit % = (70 / 400) × 100 = 17.5%.
Question 10
Easy
A housewife saved Rs. 2.50 in buying a dress on sale. If she spent Rs. 25 for the dress, approximately how much percent she saved in the transaction ?
A 8.5%
B 9.09%
C 10%
D 11.11%
Correct Answer: B

Explanation:

Amount spent = Rs. 25. Amount saved = Rs. 2.50. Original price of the dress = 25 + 2.50 = Rs. 27.50. Percentage saved = (Saving / Original Price) * 100 = (2.50 / 27.50) * 100 = (1 / 11) * 100 = 9.09%.
