In what time will a sum of money double itself at 8% p.a? Let the principal (P) = ₹ 100 ∴ Amount (A) = ₹ 100 × 2 = ₹ 200 ∴ S.I. = A - P = ₹ 200 - ₹ 100 = ₹ 100 Rate (R) = 8 % p.a. ∴ Time = `("S.I." xx 100)/("P" xx "R")` `= (100 xx 100)/(100 xx 8)` `= 25/2 = 12 1/2` years Concept: Concept for Application to Simple Interest (Time Period in Complete Years).
