1.	Amount received in certain years is three times the principal amount. Calculate the years required if it’s kept at simple interest of 12.5%.1. 12 Years2. 14 Years3. 16 Years4. 15 Years
Answer» Correct Answer - Option 3 : 16 Years Given: A = 3 × P R = 12.5% Formula used: I = PRN / 100 Where P = Principal amount, R = Rate of interest in %, N = Number of years, I = Interest earned A = P + I Where A = Amount received Calculation: Let principal amount be X, A = 3X ⇒ I = 3X – X ⇒ I = 2X Accordingly, 2X = (X × 12.5 × N / 100) ⇒ 2 = 25 × N / 200 ⇒ N = 400 / 25 ⇒ N = 16 years ∴ required time is 16 years

Answer» Correct Answer - Option 3 : 16 Years

Given:

A = 3 × P

R = 12.5%

Formula used:

I = PRN / 100

Where P = Principal amount, R = Rate of interest in %, N = Number of years, I = Interest earned

A = P + I

Where A = Amount received

Calculation:

Let principal amount be X, A = 3X

⇒ I = 3X – X

⇒ I = 2X

Accordingly,

2X = (X × 12.5 × N / 100)

⇒ 2 = 25 × N / 200

⇒ N = 400 / 25

⇒ N = 16 years

∴ required time is 16 years
