Question

In how many years will rupee 900 yield an interest of rupee 324 at 12 %per annum simple interest.?

Answer 1

Answer:

Simple Interest = Principal ( P ) × Rate % ( R ) × Time ( T ) / 100

According to the question,

Principal ( P ) = 900

Rate % = 12 %

Simple Interest = 324

Time = ?

Substituting the values in the formula we get,

⇒ 324 = ( 900 × 12 × T /) / 100

⇒ 324 = ( 10800 T ) / 100

⇒ 324 = 108 T

⇒ T = 324 / 108

⇒ T = 3 years

Hence in 3 years, Rs. 900 will yield Rs. 324 as Simple Interest with 12 % per annum.

Answer 2

Answer :

3 years

Step by Step Explanation :

Solution :-

Principal = ₹900

Rate = 12%

Interest = ₹324

Time = ?

As per problem,

I = P×R×T / 100

= 324 = 900 × 12 × T / 100

= 324×100 = 900 ×12× T

= T = 324×100 / 900 ×12

= T = 3

Therefore; Time = 3 years.
