A fruit seller makes a profit of 20% by selling mangoes at a certain price. If he charges Rs. 1 more for each mango, he can make a profit of 40% . Find the selling price of a mango in the first case = ?

A. Rs. 6

B. Rs. 5

C. Rs. 5.50

D. Rs. 7

Answer: Option A

Solution(By Examveda Team)

Let CP of 1 mango → 100

CP		SP
100	→	120	[Profit→20]
100	→	140	[Profit→40]

Difference in SP = 140 - 120 = 20
20 unit = Rs. 1
1 unit = $$\frac{1}{{20}}$$
120 unit = $$\frac{120}{{20}}$$ = Rs. 6
