please mark it as brainliest answer.

Step-by-step explanation:

3. Time = 2 1/2 years.

Solution:

Sum of amount = Rs. 8635

Principal = Rs. 7850

Simple interest = Amount - Principal

=> 8635 - 7850

=> Rs. 785

R = 4%

S.I = PNR/100

785 = (7850 * N * 4)/100

100 = 10 * N * 4

N = 100/40

N = 10/4 = 5/2

N = 2 1/2 years
