Question

rohan purchesd some cricket balls at the rate of 1000 rupees for 4 balls and sold them at the rate of 1500 rupees for 5 balls find his gain or loss percent

Answer 1

CP = Rs. 1000 / 4 BALLS

CP PER BALL = Rs. 1000/4

CP PER BALL = Rs.250

SP = Rs. 1500 / 5 BALLS

SP PER BALL = Rs. 1500/5

SP PER BALL = Rs. 300

PROFIT = 300 - 250

PROFIT = Rs. 50

P% = (PROFIT/CP)*100

P% = (50/250)*100

P% = 20%

PROFIT % = 20%
