Answer 2

Step-by-step explanation:

Given that,

Principal = Rs. 3125

Time = 3 years

Rate of interest for first, second, and third year = 4%, 5% , & 6%

As we know,

Amount = P(1+r/100)^n

=3125(1 + 4/100)(1+5/100)(1+6/100)

= 3125(104/100)(105/100)(106/100)

= 3125(26/25)(21/20)(53/50)

= Rs. 3617.25

Since

Amount Principal + Compound Interest

3167.25 = Rs. 3125+ Compound Interest

Compound Interest = Rs. 3617.25- Rs. 3125

= Rs. 492.25
