₹ 6000 becomes ₹ 7200 in 4 years at a certain rate of simple interest. If the rate becomes 1.5 times of itself, the amount of the same principal in 5 years will be
(a) ₹ 8000
(b) ₹ 8250
(c) ₹ 9000
(d) ₹ 9250
Answer Explanation $P=₹ 6000$, S.I. $=₹(7200-6000)=₹ 1200, T=4 \mathrm{yrs}$. $$\therefore \quad \text { Rate }=\left(\frac{100 \times 1200}{6000 \times 4}\right) \%=5 \% .$$ New rate $=(1.5 \times 5) \%=7.5 \%$.
