Here, Principal (P) = ₹ 1,200, Rate (R) = 12% p.a., Time (T) = 3 years
Simple Interest =(Px R x T)/100
=(1200 x 12 x 3)/100
= ₹ 432
Now, Amount = Principal + Simple Interest
= 1200 + 432
= ₹ 1,632
(b) Here, Principal (P) = ₹ 7,500, Rate(R) = 5% p.a., Time (T) = 3 years
Simple Interest =(Px R x T)/100
=(7500 x 5 x 3)/100
=₹1,125
Now, Amount = Principal + Simple Interest
= 7,500 + 1,125
= ₹ 8,625
