Hyderabad: This is a continuation of the last article focused on the subject of profit and loss. Here are practice questions along with solutions that will help you in your preparation for state government recruiting jobs.

1. The cost price of two dozen bananas is 32. After selling 18 bananas at the price of 12 per dozen, the trader reduced the price to 4 per dozen. The percentage loss is ?

a) 35.5% b) 37.5% c) 36.5% d) 38.5%
Answer: b

Solution: Total CP = 32

Total PS = (18 2) = 20
Loss = (32-20) = 12
Percentage loss = 12/32 × 100 = 37.5%
2. Ramesh bought 10 cycles for Rs 500 each. He spent Rs 2,000 for the repair of all the cycles. He sold five for Rs 750 each and the rest for Rs 550 each. So the total gain or loss % is?
a) Loss of 7 1/7% b) Gain of 5 2/3% c) Loss of 5 1/3% d) Gain of 7 1/3%

Answer: one
Solution: Total actual PC = (500 × 10 2000) = 7000
And total SP = (5 × 750 5 × 550)

= (3750 2750) = 6500

Loss = 7000 – 6500 = 500

Loss percentage = 500/7000 × 100

= 50/7 = 7 1/7%

3. By selling 17 balls at 720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is ?
a) 60 b) 50 c) 40 d) 30

Answer: one

Solution: Let the CP of each ball = x

So, clearly the cost price of (17 – 5) balls = 720
i.e., 12x = 720
=> ; x = 60
i.e. 60
4. I bought 120 notebooks at 3 each and sold 1/3 at 4 each, 1/2 at 5 each and the rest at cost price. My profit percentage was ?

a) 44 2/3% b) 44 4/9% c) 44 1/4% d) 45 2/7%

Answer: b
Solution: CP of 120 notebooks = (120 × 3) = 360
SP from 40 to 4 each = (40 × 4) = 160

SP from 60 to 5 each = (60 × 5) = 300

SP of the remaining 20 books = (20 × 3) = 60

Total PS = (160 300 60) = 520

Profit % = (520 – 360) = 160

 Profit % = 160/360 × 100

= 400/9 = 44 4/9%

5. A man bought pencils at the rate of 6 to 4 and resold them at the rate of 4 to 6. His % gain in the transaction is ?

a) 60% b) 80% c) 100% d) 125%

Answer: d
Solution: Let the number of pencils purchased = LCM of 4, 6 = 12
CP of 6 pencils = 4

 CP of 12 pencils = 8

SP of 4 pencils = 6

 SP of 12 pencils = 18

Profit = Rs (18 – 8) = 10

Profit % = 10/8 × 100 = 125%
