Question

find simple interest and amount whose principal is 1200 rate 12% time 3 years

Answer 1

Here, Principal (p)= Rs 1200
rate (r) = 12 %
time (t) = 3 years.
So, SI = prt /100
= 1200 × 12 ×3 /100
Therefore , interest =Rs 432.
2ndly; Amount = p + interest.
Amount= Rs 1200 + 432
Amount = Rs1632/-

Answer 2

principal=rs 1200
rate=12%
time=3 yrs
S.I=P×R×T/100
S.I=1200×12×3/100
S.I=₹432
Amount=S.I+principal
Amount=₹1200+432
=₹1632
