Question

A shopkeeper purchased 24 marbles for rs 12 and sold 20 marbles for rs 15 find his gain percent

Answer 1

Answer:

your answer is below with step by step

Solution= Given that cp of 24 marbles=12 rupees

Therefore cp of one marble= 24/12=2 rs

Then cp of 20 marbles= 20 * 2 is equal to 40

And also given sp of 20 marbles = 15

then sp of 1 marble =20/15=2/3 rupees

here cp of one marble = 2

and sp of one marble = 2/3

since cp is greater means loss

loss = Cp-sp

=2-2/3

=4/3

loss% = 4/3/2*100%

=4/3*1/2*100

=4/3*1*50

=200/3

=66 whole 2/3 Answer
