Question

A man purchase some egg at 3 for rs16 and sold them at 5 for rs36 thus he gain 168 in all. how many egg did he purchase

Answer 1

Let the number of eggs purchased be x.

Given: C.P of 3 eggs= Rs 5
⇒C.P of x eggs= Rs
5/3x
and S.P of 5 eggs= Rs 12.
so, S.P of x eggs = Rs
12/5x
Now profit = S.P - C.P
⇒143 = 12x/5-5/3x
⇒143 = 36x-25x/15 = 11/15x
⇒143×15/11 = 195
Hence the man purchased 195 eggs.
