Question

How much time for an amount of 450 to yeild 81 as interset at 4.5% per annum of simple interset

Answer 1

Answer:

Time (T) = 4 years

Explanation:

Principal (P) = Rs450

Rate of interest (R) = 4.5%

Simple interest (I) = Rs81

Let the time = T years

We know that,

(PTR)/100= I

=> T = ( I × 100 )/(PR)

=> T = (81 × 100)/(450×4.5)

=> T = (81×100)/(45×45)

After cancellation, we get

=> T = 4 years

Therefore,

Time (T) = 4 years
