Question

50. A fruitseller purchases lemons at the rate
of 2 lemons for 1 and sells at the rate of 5
lemons for 3. What is his percentage
profit?
(A) 8%
(B) 10%
(C) 15%
(D) 20%​

Answer 1

Ans. is 20%

Here's solution

We know that cost price(cp) of 2 lemons is 1 RS.

Now, he sells 5 lemons at 3 RS

So,

5 lemons =3 RS

2 lemons = x RS

By cross multiplying we get

5x= 6 & x=6/5

Therefore, Selling price(sp) of 2 lemons is 6/5 RS

Now Profit% = (sp-cp/cp) *100

=(6/5–1/5)*100

=1/5*100

=20%

So profit earned by seller is 20%

Shortcut Method:

5 lemons= 3 RS

So 2 lemons = 6/5 RS.

Now 1 cp= 6/5 sp

Therefore, cp/sp= 6/5

So from 5 to 6 there is profit of 1 unit over 5

Therefore profit= 1/5 & in % it is 1/5 *100 = 20%
