**Given:** – P = ₹ 1500, R = 12% p.a. and

Time = 3 years 3 months

We know that, 1 year = 12 months

∴ 3 years 3 months = (39/12) = (13/4)

If interest is calculated uniformly on the original principal throughout the loan period, it is called simple interest.

**SI = (P × R × T)/100**

= (1500 × 12 × (13/4))/ 100

= 1500 × 12 × (13/4) × (1/100)

= (1500 × 12 × 13 × 1)/ (4 × 100)

= (15 × 3 × 13 × 1)/ (1 × 1)

= (15 × 3 × 13 × 1)

= ₹ 585

**Amount = (principal + SI)**

= (1500 + 585)

= ₹ 2085
