$\huge\red{Answer}$

Simple Interest (I) = The interest paid on the original sum of money borrowed or invested.

I = (P × R ×T)/100

Principal (P) = The sum of money lent, borrowed or invested.

Time (T) = The duration for which the sum of money is lent invested , usually in years.

Rate(R) = The interest paid on ₹ 100 per unit of time ,usually per annum (p.a).

Amount (A)= The sum of the principal and the interest.

A = P + I

SOLUTION :

GIVEN : P = ₹3500, A= ₹4130, R = 6%,

I  = A - P

I = 4130 - 3500

I = ₹ 630

I = (P × R ×T)/100

630 = (3500 × 6 × T)/100

630 × 100 = 3500 × 6 × T

63000 = 3500 ×6 × T

T = 63000 /( 3500 ×6)

T = 630/ 35×6  = 105/35 = 3 years
