Question

I sold a book at a profit of 12 percent had I sold it for RS.18 more 18percent would have been gained find the CP

Answer 1

let CP = 100%
Sold on 12% profit means sold on 112%
now 18% would have been gained means 118% if Rs 18 was more
it means 118% - 112% = 18 Rs
so 6%=18Rs
so 100% = (18/6)×100 = 3× 100 = 300 Rs
CP = 300 Rs

Answer 2

Answer:

Cost Price of product is Rs. 300

Step-by-step explanation:

Hey Mate,

Cost Price is 100% price of Product.

A book sold at 12% profit

Suppose, 12% Profit = Rs. X

If its sold for Rs 18 more then he gain 18%.

So, 12% + Rs.18 = 18%

(18 - 12)% = Rs. 18

6% = Rs. 18

1% = Rs. 3

So,

100% = 3 × 100 = Rs. 300 = C.P

Cost Price of product is Rs. 300
