Question

principal amount Triple itself at 8% annual over a certain time.find the number of years?​

Answer 1

Step-by-step explanation

A = p * ( 1 + RT/100 )

3p = p * ( 1 + 8T/100 )

3 = 1 + 8T/100

2 = 2T/25

1 = T/25

T = 25 years

Answer 2

Answer:

25

Step-by-step explanation:

Let the principal amount be P

Given :

Amount ( A ) = Triple the Principal amount = 3P

Rate of interesf = 8 %

Time ( T ) = ?

We know that

⇒ A = P( 1 + TR / 100 )

⇒ 3P = P( 1 + 8T / 100 )

⇒ 3 = 1 + 8T / 100

⇒ 3 - 1 = 2T / 25

⇒ 2 = 2T / 25

⇒ 1 = T / 25

⇒ 25 = T

Therefore the number of years are 25 years.
