P = Principal amount

R = rate of interest

T = Time period

S.I = (P × R × T)/100

Given:

P = Rs. 4860

R = 20%

T_{1} = 6 years

T_{2} = 5 years

A.T.Q

**⇒ x = S.I for 6 years**

⇒ x = (4860 × 20 × 6)/100

⇒ x = 583200/100

⇒ x = 5832

**⇒ y = S.I for 5 years**

⇒ y = (4860 × 20 × 5)/100

⇒ y = 486000/100

⇒ y = 4860

**Thus x - y = (5832 - 4860) = Rs. 972**
