Answer: RS 168

Step-by-step explanation:

Let C.P. = Rs. P  

S.P. = (C.P.) - (Loos) = P - P/7 = Rs. 6P/7

∵ 6P / 7 = 144

∴ P = (144 x 7) / 6 = Rs. 168

Hence, no Loss and no gain

Answer:

Step-by-step explanation:

By selling an article for rs144, a man loses 1/7 th of his outlay.

Let the cost price be x

then. x - (1/7)x =144

x - x/7 = 144

7x-x/7 = 144

6x/7 = 144

6x = 144×7

x= 144×7/6 = 168 is the cost price..

If it is sold for rs 189, selling Price= 189

Selling Price>cost price

189>168

so profit exists

Profit /Gain

= selling Price - cost price

= 189 - 168

= 21

Gain Percentage = (Gain/cost price)×100

=(21/168)×100

=2100/168

=12.5%
