Question

A man sold 10 eggs for rs.5 and gained 20% how many eggs did he buy for 5 rupees

Answer 1

Hi ,

i ) selling price of 10 eggs = sp = Rs 5

gain = g = 20%

Let Cost price of 10 eggs = Rs x

x = ( sp × 100)/ ( 100+ g )

= ( 5 × 100 ) / ( 100 + 20 )

= 500/ 120

x = 50/12

ii) By unitary method

The man buys number of eggs

with Rs 50 /12 = 10


How many eggs he buys with Rs 5 ?


Number of eggs the man can buy

With Rs 5 = ( 5 × 10 × 12 )/ 50

= 12

I hope this helps you.
