Question

a man sells 320 mangoes at the cost price of 400 mangoes his gain percentage is

Answer 1

Let the man sell each mango @rs1
rs320= 400 mangoes
cp of 1 mango is 320/400 = 0.8
profit = sp-cp
=0.2
profit %=profit/cp*100
=0.2/0.8*100 = 25%

Answer 2

"Let CP of 1 mango be rs. 1

SP of 320 mangoes = CP of 400 mangoes = 400

CP of 320 mangoes = 320

Gain = 400 - 320 = 80

Gain % = 80 / 320 * 100

= 8 / 32 * 100

= 100 / 4

=25%

Hence, the gain percentage of the mangoes will be 25
