Answer 2

Answer:

2.5 year

Step-by-step explanation:

we know ,

simple interest = P×R×T/100

Here,

p= principal

R= Rate of interest per annum

T = time

Also, amount (A)= P+S.I

= 55=50+50×4×T/100 ( we have to put the values in the formula of amount )

55 = 50+200×T/100

= 50+2T

5= 2T

T = 2.5 years
