Question

the cost price of 15 water is equal to the selling price of 12 water then find the profit and loss percentage

Answer 1

CP of 15 = SP of 12

Let CP of 1 be Rs. 1

CP of 12 be Rs. 12

CP of 15 be Rs. 15

SP of 12 be Rs. 15

Gain= 3

Gain% = 3/12 X 100

=25%

Answer 2

let the cost price of 15 l water be x
then selling price of 12 l water will be x
so the cost cost price of 1 l water =x/15
then the cost price of 12 l water will be =12x/15
so the profit will be x-12x/15
profit %=3x/15×15/12x×100
p%=25%
