Question

in how many years wil the sum rupees 1500 to rupees 1770 at a rate of 6% per annum

Answer 1

Solution :

Given ,

principal ( p ) = Rs 1500,

Amount ( A ) = Rs 1770

Simple interest ( I ) = A - p

= Rs 1770 - Rs 1500

= Rs 270

Rate of interest ( r ) = 6%

Let the time = t years

( ptr )/100 = I

=> t = ( 100 × I )/( pr )

= ( 100 × 270 )/( 1500 × 6 )

= 270/( 15 × 6 )

= 3

Therefore ,

Time ( t ) = 3 years
