Question

find the sum which earned rs.1200 as simple interest in 5 years, rate of interest being 12 percent per annum

Answer 1

Hey...!!!

S.I = Rs 1200

Time = 5 years

Rate of interest per annum = 12 %

So, Principal = S.I x 100 / T x R

= 1200 x 100 / 5 x 12

= 2000

So, principal = Rs 2000

Hope it helps...!!,

Answer 2

Simple Interest=Principal×Rate×Time/100

By applying the Formula to find the Principal

So,

Principal=Simple Interest×100/(Rate×Time)

=1200×100/(12×5)
Principal=₹2000

So it will be ₹2000
