Question

2. A washing machine was marked 40% above cost price and a discount of 35% was given on
marked price. Find the gain or loss per cent.
​

Answer 1

Step-by-step explanation:

let the cost price of the machine be x. so there is 9% loss

Answer 2

Step-by-step explanation:

let the cp be x

we have,

Mp=cp+40% of cp

Mp=x+40÷100×x

Mp=x+2x/5

mp=( 5x+2x)÷5

mp= 7x/5

Then,

sp =mp_d% of mp

=7x/5-3/100×7x/5

=679x/500

Again,

p%= sp-cp/cp×100%

35.8%
