Question

A sum amounted to rs.8160 at 6% p.A. For the period of 6 years. Find the sum.

Answer 1

Solution :

Let the principal = P

Rate of interest (R) = 6%

Time ( T ) = 6 years

Amount ( A ) = 8160

We know that ,

P[ 1 + TR/100]= A

=> P[ 1 + 6×6/100]= 8160

=> P ( 1 + 36/100) = 8160

=> P × 1.36 = 8160

=> P = 8160/1.36

=> P = 6000

Therefore ,

Principal = P = Rs 6000
