Question

On selling a photo frame for Rs 144,shopkeeper loses 1/7 of his outlay, If it is sold for Rs189 ,how much will be the gain per cent? ​

Answer 1

Step-by-step explanation:

Given :

Selling Price Of a Photo Frame Rs 144

Find :

Gain Percent

Solution :

Let the Cost Price Of Photo Frame be Rs X

Loss X × 1/7

Loss X / 7

Now Applying Loss Formula

Loss = CP - SP

X / 7 = X - 144 or 144 = 6x / 7

Now Applying Cross Multiplication Method

144× 7 = 6x × 1

1008 = 6x

X = 1008 / 6 ( Cancel 6 by 1008 )

X = 168

Now Selling price = Rs 168

Profit = Rs 21

Now Applying Profit %

Profit % = Profit / CP × 100

Therefore Profit % = 21 / 168 × 100

Therefore Profit % = 524 / 42

Therefore Profit % = 12.5 %

The Gain Percent is 12.5%
