By selling a book for Rs. 144 a man loses 1/7 of his outlay. If he sells it for Rs 189, then his Gain percentage is 12.5%

Note : A man loses 1/7 of his outlay. Not 1/2.

Step-by-step explanation:

Let the Cost Price be ₹ P

Loss on Cost Price = 1/7 = P/7

Selling Price = ₹144

Selling Price= Cost Price - Loss

=> 144 = P - P/7

=> 144 = (7P-P)/7

=> 144 = 6P/7

=> P = (144x7)/6

=> P = ₹168

Cost price = ₹168

If he sells the book for ₹189 :

Cost Price = ₹ 168

Selling Price = ₹ 189

Selling Price is more. Hence, Profit occurred.

Profit = SP - CP

Profit = 189 - 168

Profit = ₹21

Profit Percentage = (Profit/CP) x 100

Profit Percentage = (21/168) x 100

Profit Percentage = 12.5%
