In 4 years, ₹ 6000 amounts to ₹ 8000. In what time at the same rate will ₹ 525 amount to ₹ 700?
(a)2 years
(b)3 years
(c)4 years
(d)5 years
Answer
Explanation
$P=₹ 6000$, S.I. $=₹(8000-6000)=₹ 2000, T=4$ years. $$\therefore \quad \text { Rate }=\left(\frac{100 \times 2000}{6000 \times 4}\right) \%=\frac{25}{3} \%=8 \frac{1}{3} \% .$$ Now, $P=₹ 525$, S.I. $=₹(700-525)=₹ 175, R=8 \frac{1}{3} \%$. $$\therefore \quad \text { Time }=\left(\frac{175 \times 100 \times 3}{525 \times 25}\right) \text { years }=4 \text { years. }$$
