Answer 1

Answer:

Let CP be X. SP will be 1.25X.(25%) profit.

New CP is (X+20). New SP is (1.25X+4). New profit is 10% less is 15%. (SP-CP)*100/CP is profit.

{(1.25X+4)-(X+20)}*100/(X+20)=15

(1.25X+4-X-20)*100=15(X+20)

25X-1600=15X+300. Solving for X we get 190. So cost price is Rs 190.00

Answer 2

Answer:

₹190

Let CP be X. SP will be 1.25X.(25%) profit.

New CP is (X+20). New SP is (1.25X+4). New profit is 10% less is 15%. (SP-CP)*100/CP is profit.

{(1.25X+4)-(X+20)}*100/(X+20)=15
