Question

A machine is sold at a profit of 20%. If it had been sold at a profit of 25%, it would have fetched Rs. 35 more. The cost price of the machine is a) Rs. 650 b) Rs. 7 00 c) Rs. 750 d) Rs. 800

Answer 1

The answer of your question is 700
According to me

Answer 2

let cp be x
sp when profit is 20 percent = x+(1/5×x)
sp when profit is 25 percent =x+(1/4×x)
difference between the two =35
so x+1x/4- (x+1x/5)=35
1x/4-1x/5=35

x/20=35


x=20×35

x=700

CP of the article is 700

hence the answer is b
