A bought a tape recorder for Rs 8,000 and sold it to B. B in turn sold it to C, each earning a profit of 20%. Which of the following is true
(a) A and B earn the same profit
(b) A earns more profit than B
(c) A earns less profit than B
(d) Cannot be decided
Solution:
The Cost Price(CP) of tape recorder to A = Rs. 8000
The price at which A sells to B = 8000 + 20% of 8000 (profit of 20%)
= 8000 + (20/100) × 8000
= 8000 + 1600
= Rs. 9600
Profit earned by A = Rs.(9600 - 8000) = Rs. 1600
The cost price of the tape recorder to B is therefore Rs. 9600
The price at which B sells to C = Rs. 9600 + 20% of 9600
= Rs. 9600 + (20/100) × 9600
= Rs. 9600 + Rs. 1920
= Rs. 11,520
Profit earned by B = Rs.(11,520 - 9600) = Rs. 1920
The profit earned by B is more than A.
✦ Try This: A bought a tape recorder for Rs 8,000 and sold it to B. B in turn sold it to C, each earning a profit of 25%. Which of the following is true: (a) A and B earn the same profit, (b) A earns more profit than B, (c) A earns less profit than B, (d) Cannot be decided.
The Cost Price(CP) of tape recorder to A = Rs. 8000
The price at which A sells to B = 8000 + 25% of 8000 (profit of 20%)
= 8000 + (25/100) × 8000
= 8000 + 2000
= Rs. 10,000
Profits earned by A = Rs.(10,000 - 8,000) = Rs. 2000
The cost price of the tape recorder to B is therefore Rs. 10,000
The price at which B sells to C = Rs. 10,000 + 25% of 10,000
= Rs. 10,000 + (25/100) × 10,000
= Rs. 9600 + Rs. 2500
= Rs. 12,500
Profit earned by B = Rs.(12,500- 10,000) = Rs. 2500
Profit earned by B more than profit earned by A
