Question

find the ratio of question no 11

Answer 1

CP of 5 radio sets = 320

CP of 1 radio will be 64

SP of 2 radio at a loss of 25% = 2*64*3/4 = 96

We need an overall profit of 25%

So he should sell all the 5 sets for 320*5/4 = 400

He already sold 2 and got Rs96. So remaining amount = 400-96 = 304

CP of 3 radio sets will be 3*64 = 192

Profit % = (304-192)/192 * 100

=58.33%
