From the question,
Shanta borrowed ₹ 6000 from the State Bank of India (Principal)
Time = 3 years 8 months
We know that, 1 year = 12 months
∴ 3 years 8 months = (44/12) = (11/3)
SI = 12 % .p.a.
First we have to find Simple Interest,
SI = (P × R × T)/100
= (6000 × 12 × (11/3))/ 100
= 6000 × 12 × (11/3) × (1/100)
= (6000 × 12 × 11 × 1)/ (3 × 100)
= (60 × 4 × 11 × 1)/ (1 × 1)
= (60 × 4 × 11 × 1)
= ₹ 2640
Amount = (principal + SI)
= (6000 + 2640)
= ₹ 8640
∴The amount will clear off her debt is ₹ 8640
