Answer 1

Answer:

Step-by-step explanation:

Let the sum of money that's principal be x.

Time = 6years

Amount after 6 years becomes double = 2x

Therefor, Simple Interest = Amount - Principal = 2x-x = x

Rate per annum = SI×100/ P×T = x×100/x×6 = 100/6 = 50/3 = 16.66 % approx

principal =x

Time = 6 yrs

amount after 6 yrs get double=2x

S.I=A-P=2x-x=x

Rate per annum =S.I×100/p×T=x×100/X×6=100×6=100/6=50/3=16.66%
