Answer 1

Answer:

if the answer is helpful then please mark me has brainlist

Step-by-step explanation:

Let the Principal be x

Amount is given to be 2x

Simple Interest = Amount - Principal

Simple Interest = x

WE KNOW,

TIME = (SI × 100) / ( P × R )

T = x × 100 / x × 4

T = 100x / 4x

x will cancel out

T = 100/4

T = 25 years

ANSWER = 25 YEARS
