Question

a man buys toffees at 10 for rupees 3 and sells them at 843 find his gain percent​

Answer 1

Step-by-step explanation:

suppose he bought 40 toffees.

cost price of 40 toffees=3×40/10= Rs12

SP of 8 toffees is Rs 3

SP of 40 toffees= 40×3/8= Rs 15

Gain percent= 100× Gain/CP

= 100×(15-12)/12

=100×3/12

=100/4

= 25%
