Question

karim sold a shirt at a loss of 10%. if he had sold it for 60 more, he would have gained 5% on it. find the cost price of the shirt.

Answer 1

Let the cost of the shirt be Rs x

Kunal sold the shirt at 10% loss

Hence cost of shirt after loss = x – 10% of x

                                              = (90x/100) = (9x/10)

Gain on Rs x is 5%

Cost of shirt after the gain = x + 5% of x

                                           = x + (5x/100)

                                           = 21x/20

Hence (9x/10) + 60 = (21x/20)

(21x/20) – (9x/10) = 60

3x/20 = 60

x = 60 × (20/3) = 400

Hence the cost of the shirt is Rs 400.

Answer 2

Answer:

₹400

Step-by-step explanation:

let the cp be ₹x

loss 10%

sp1= (100-l%)*cp/100

=(100-10)×x/100

90x/100

p%=5%

sp2 = (100+5)×x/100

105x/100

sp2-sp1 = 60

105x/100 -90x/100 = 60

15x/100 = 60

x = 60×100/15

x = 4×100

x = 400
