Question

At what rate percent of simple interest per annum will a sum of money triple in 6 yr?
​

Answer 1

Answer:

33 1/3 % p.a.

Step-by-step explanation:

let the principal or sum of money be x then amount after 6 yrs = 3x

so S.I. = A - P  = 3x-x = 2x and let the rate of interest be r

ATQ,

S.I. = PRT/100

2x = x r 6/100

200x = xr6

r = 200x/6x = 200/6 = 100/3 = 33 1/3 % p.a.
