Question

A man purchased some eggs at 3 for 16 and sold them at 5 for 36 Thus he gained 168 in all How many eggs did he purchase Hint let the number of eggs bought be x then CP 163 x 16x3 and SP 365 x 36x5

Accepted Answer

Let us consider the number of eggs as x

The CP of 10 eggs = ₹16x

CP of 1 egg = ₹16x/3

SP of an egg = ₹36x/5

Since SP is more than CP so it’s again.

Gain = SP – CP = (36x/5) – (16x/3) = 168

By taking the LCM 5 and 3 we get, (108x-80x)/15 = 168

∴ 28x =168 × 15

x = (2520) /28

x = 90

∴ the number of eggs is 90
