a) 4 years 5 months
b) 5 years 4 months
c) 6 years 2 months
d) 6 year 5 months
Answer: b
Explanation:
$$\eqalign{
& {\text{Let sum = Rs}}{\text{. }}x{\text{}} \cr
& {\text{S}}{\text{.I}}{\text{. = Rs}}{\text{. }}x{\text{}} \cr
& \text{Time} = \left( {\frac{{100 \times {\text{S}}{\text{.I}}{\text{.}}}}{{{\text{P}} \times {\text{R}}}}} \right) \cr
& = \left( {\frac{{100 \times x}}{{x \times 18.75}}} \right){\text{years}} \cr
& = \frac{{26}}{3}{\text{years}} \cr
& = 5\frac{1}{3}{\text{years}} \cr
& = {\text{5 years 4 months}}{\text{}} \cr} $$
