Question

A dealer purchased a washing machine for rupees 15320. He allwos a discount of 12℅ on its marked price and gain 10℅ on it . find the marked price of the machine ?

Answer 1

let mp of the machine is rs 100X

100X - 100X×12/100

=100X - 12X

= rs. 88X (selling price )

if CP is 100 then SP is (100+10) = 110

if CP is rs 1 then SP is 110/100

if CP is 15320 then SP is

$110 \times \frac{15320}{100}$

= rs 16852

$\frac{88x}{100 } = 16852$

$x = \frac{16852 \times 100}{88}$

x= 383×50

x= 19150
