Question

Renu sold a Silk dress for rupees 960 and gain an amount equal to one-ninth of its cost price find (i) the cost price of the dress and (ii) the gain percent and by Renu

Answer 1

I Think this Answer is approximatly

right because I didn't include Decimals in it.

so let's start

now

Profit (here ) = 1/9 of Cp (CP = SP - Profit)

Profit = 1/9 X SP - Profit

Profit + Profit = 1/9 X 960 (SP = 960)

Let profit be x over here

x + x = 106

2x = 106

x = 106 /2

x = 53

Now CP is equal to SP - Profit

960 - 53 = 907

Now

Gain % = Gain X 100/CP

Gain % = 53 X 100/907

Gain % = 5.84 % ( By Calculation )

Here's your answer

Don't forget to follow me
