Answer 2

Step-by-step explanation:

let the sum be X = Principal Amount

I) Amount 800 , Rate 3% Time = T

Then Intrest = Amount - Principal Amount

= 800- X

S.I = Principal Amount *R*T/100

800-X = X * 3 * T /100. equation (I)

similarly

ii) 1000- x = 5 *x *T /100. equation (ii)

Now substract equation i from ii

200 = 2* X*T /100

x = 10000/ T

Put value of X in equation (i)

800- x = 3*10000/100

x = 500 Principal Amount

x = 10000/T

500= 10000/T

T = 10000/500= 20 Years
