Question

- A man purchases 12 eggs for Rs. 20 and sells 5 eggs for Rs. 12. If he purchases and sells
definite number of eggs, then calculate his gain per cent.​

Answer 1

Let us assume he bought 6 eggs -------- LCM of 2 and 3

CP of 6 eggs @ 2 for Rs 1 = Rs 3

CP of 6 eggs @ 3 for Rs 2 = Rs 4

Total CP = 3 + 4 = Rs 7

Total eggs = 6 + 6 = 12

SP of 12 eggs @ 5 per Rs 3

= 3/5 × 12 = 36/5 = 7.20 Rs

Profit = 7.20 – 7

= 0.20 Rs

Profit % = 0.2×100/7 = 2
