10. Romit sold his old TV and earned profit of 10% . If he could have managed to sell it for Rs. 8100 more, his profit would have been be 37%. Find the price at which he bought the TV?
a. Rs. 30000
b. Rs. 41000
c. Rs. 44500
d. Rs. 55000
Answer: a. Rs. 30000
Explanation:
1st profit = 10%
If Romit sells TV for Rs. 8100 more, then profit = 37%
SP = (100 + Profit %) % of CP
∴ SP1 + 8100 = SP2
∴ (110) % CP + 8100 = (137) % CP
∴ 27% of CP = 8100
| ∴ CP = | 8100 x 100 | = Rs. 30000 |
| 27 |
