Question

do it as fast a.s possible..​

Answer 1

Step-by-step explanation:

marked value = 280

discount = 10%

then founded,

280 - 280 × 10% = 280 - 28 = 252

but shopkeeper found 26 % profit on 252

now suppose actual cost = x

then,

x + x × 26% = 252

126 x / 100 = 252

x = 252 × 100 / 126 = 200

answer = Rs 200
