Description for Correct answer:
With smart approach
Principal Amt.=Rs. 25000
Time = 2 years
R1 = 4 %, R2 = 5 % Annually
\( \Large 4 %=\frac{1}{25}, 5 %=\frac{1}{20} \)
So amount will be Rs. 27300 after 2 years
Part of solved Simple and compound interest questions and answers : >> Aptitude >> Simple and compound interest
The amount on Rs. 25,000 in 2 years at annual compound interest, if the rates for the successive years be 4% and 5% per annum respectively is: (1) Rs. 30,000 (2) Rs. 26,800 fa) Rs. 27.300 (4) Rs. 28,500
Correct Option: C
Given that , Principal = Rs. 25,000 , Time = 2 years , R1 = 4% , R2 = 5%
Using the given formula ,
| Amount = P | 1 + | R1 | 1 + | R2 | ||||
| 100 | 100 |
| Amount = 25000 | 1 + | 4 | 1 + | 5 | ||||
| 100 | 100 |
| Amount = 25000 × | 104 | × | 105 |
| 100 | 100 |
