Answer 2

Solution :-

Let us assume that, rate of interest is R% per annum .

So,

→ P = Rs. 50000

→ A = 3 * 50000 = Rs. 150000

→ T = 6 years

then,

→ A = P[1 + (R/100)]^T

→ 150000/50000 = [1 + (R/100)]⁶

→ 3 = [1 + (R/100)]⁶

→ 3^(1/6) = 1 + (R/100)

→ 1.2 - 1 = (R/100)

→ 0.2 * 100 = R

→ R ≈ 20% (Ans.)
