(d) Rs. 2,250
Show Answer & Explanation

Answer: (a) Rs. 2,750

Explanation:
1. 10 quintals = 1000 kg.

3. Profit = 11,500 - 8,750 = 2,750.

Teacher's Note:
1. 1 quintal = 100 kg.

Show Answer & Explanation

Answer: (d) Rs. 84

Explanation:

3. Profit = 240 - 156 = 84.

Teacher's Note:
1. There are 120 pencils in all.
2. Profit = S.P. - C.P.

Question 19: Bela buys a car for Rs. 89,000, spends Rs. 21,000 on repairs and sells it for Rs. 1,10,000. She has:
(a) a profit of Rs. 21,000

Teacher's Note:
1. Overhead expenses are added to the cost price.
2. Compare total C.P. with S.P.

Question 20: C.P. = Rs. 500 and S.P. = Rs. 600. The profit percent is:
(a) 10%
(b) 20%
(c) 16 2/3 %
(d) 120%
Show Answer & Explanation

Answer: (b) 20%

Explanation:
1. Profit = 100; 100/500 × 100 = 20%.

Teacher's Note:
1. Profit percent is always calculated on C.P.
2. Profit = 600 - 500 = 100.

Question 21: C.P. = Rs. 600 and S.P. = Rs. 500. The loss percent is:
(a) \( 16\frac{2}{3}\% \)
(b) \( 20\% \)
(c) \( 15\% \)
(d) \( 12\frac{1}{2}\% \)
Show Answer & Explanation

Answer: (a) \( 16\frac{2}{3}\% \)
