Answer:
The compound interest for the same sum
for 2.5 years is Rs. 2259.6
Step-by-step explanation:
The Simple Interest, SI = 2940
Time, n = 3.5 years
Rate of Interest, r = 10%
The principal, P, is calculated as:
SI = Prn/100
2940 = (P * 10 * 3.5) / 100
P = (2940 * 100) / 35
= 8400
Thus, the Principal is Rs. 8400.
The compound interest for the same sum in 2.5 years is calculated as follows;
CI = Amount -Principal
Amount =
[P (1+r/100)) ^2.5
Thus,
CI= [P (1+r/100)) ^2.5 - P
= 8400 ((1+10/100)) ^2.5 - P
= 8400 ((110/100)) ^2.5 - 8400
=(8400* 1.269) - 8400
= 10659.6 - 8400
= 2259.6
Thus, the compound interest for the same sum for 2.5 years is Rs. 2259.6
