Answer 1

Q. Naveen brought some cricket balls at ₹ 250 for 4 balls and sold them at ₹ 340 for 5 balls. Find his gain or loss per cent.

Solution :

C.P of 4 balls = ₹ 250
C.P of 1 ball = ₹ 250/4 = ₹ 62.50

S.P of 5 balls = ₹ 340
S.P of 1 ball = ₹ 340/5 = ₹ 68

Here,
S.P > C.P

Hence,
Profit = S.P - C.P
Profit = ₹ 68 - ₹ 62.50 = ₹ 5.50

So,
Profit % = [ Profit/C.P ] × 100

Profit % = [ 5.50/62.50 ] × 100

Profit % = 44/5 % = 8 whole 4/5 %

Hence,
Profit % = 44/5 %

Answer 2

Hey mate!

Here's your answer!!

The Cost Price of the ball CP,
= 250/4
= 62.5 Rs.

The Selling Price of ball SP,
= 340/5
= 68 Rs.

He has sold the balls at higher price, hence their is a gain of (68 - 62.5) = 5.50Rs.

Gain %
= 5.50 × 100 / 62.5
= 44/5 %
