Answer 2

Answer:

Rs.560

Step-by-step explanation:

Cost price of 1 ball = Rs.40

Number of balls = 30

He sold 20 balls

Remaining balls = 30-20 = 10

CP of 10 balls = $40 \times 10 = Rs.400$

Profit % = 40%

$SP =\frac{CP(100+P\%}{100}$

$SP =\frac{400(100+40}{100}$

$SP =560$

Hence he should sell at Rs.560.
