---

a) 64 4/3% b) 33 1/3% c) 425% d) 50%

Ans: d
Solution: Let the CP of each pen be 1
CP of 8 pens = 8

SP of 8 pens = 12

 Gain % = 4/8 × 100 = 50%

2. A man sells 320 mangoes at the cost price of 400 mangoes. His gain percent is?
a) 10% b) 15% c) 20% d) 25%
Ans: d

Solution: Gain per cent

= (400 – 320)/320 × 100
= 80/320 × 100 = 25%
3. The cost price of 8 articles is equal to the selling price of 9 articles. The profit or loss per cent in the transaction is?

a) 12 1/2% profit b) 11 1/9 % profit c) 12 1/2% loss d) 11 1/9% loss

Ans: d
Solution: Let the CP of each article be 1
 CP of 9 articles = 9

 SP of 9 articles = 8

 Loss = 1

 Loss % = 1/9 × 100

= 100/9 = 11 1/9%

4. If the cost price of 10 articles is equal to the selling price of 7 articles, then the gain or loss per cent is?

a) 42 6/7% gain b) 23 2/5% gain c) 42 6/7% loss d) 23 2/5% loss

Ans: a

Solution : Let CP of each article be 1

Then, CP of 7 articles = 7
SP of 7 articles = 10
 Gain % = (10 – 7) / 7 × 100 = 3/7 × 100
= 300/7 = 42 6/7%
5. A sold an article to B at 20% profit and B sold to C at 15% loss. If A sold it to C at the selling price of B, then A would make?

a) 2% profit b) 2% loss c) 5% loss d) 5% profit

Ans: a

Solution: CP of article for A = Rs 100

A’s SP = 100 × 120/100
= Rs 120

B’s SP = 120 × 85/100

= Rs 102

= CP for C

 Required profit percent = 2%

6. Somesh purchased a radio at 9/10 of its selling price and sold it at 8% more than its original selling price. His gain per cent is?
a) 5 % b) 8% c) 13 % d) 20 %

a) 13.3% b) 37.5% c) 22.5% d) 45.3%
Ans: b

Solution: If the CP of A articles be equal to SP of B articles, then

Loss percent = B – A / B ×100
= 16 – 10 / 16 × 100 = 6/16 × 100

= 37.5%
