Question

In how many years will rupees$150 double itself at 4% simple interest?​

Answer 1

Answer:

Time = t yrs

Principal = $150

Rate of interest = 4%

Amount = double of principle

= 2× 150

= $ 300

Ans . S.I. = Amount-Principal

s.i. = $300-$150

= $150

we also know that

S.I. = PRT / 100

$ 150 (S.I. ) = 150×4×t / 100

= 6t

6t = 150

t = 150/6

= 25

So, The the time taken = 25 years
