Solution

₹ 550

Explanation;

Hint:

If selling price (S.P) = ₹ 528

Gain % = 20%

∴ C.P = ?

Selling price (S.P) = `"C.P" xx ((100 + "gain"%)/100)`

∴ 528 = `"C.P" xx (100 + 20)/100`

∴ C.P = `(528 xx 100)/120` = 440

If gain % = 25%, Selling price = ?

Selling price (S.P) = `"C.P" xx ((100 + "gain"%)/100)`

= `440 xx ((100 + 25))/100`

= `440 xx 125/100`

= ₹ 550
