Correct Answer – Option 1 : 4 : 15
Given:
Rate = 75%
Formula used:
For 2 years, CI – SI = P(r/100)2
for 3 years, CI – SI = P(r/100)2 [(300 + r)/100]
Calculation
(CI – SI) for 2 years : (CI – SI) for 3 years = P(r/100)2 : P(r/100)2 (300 + r)/100
⇒ (CI – SI) for 2 years : (CI – SI) for 3 years = 100 : (300 + r)
⇒ (CI – SI) for 2 years : (CI – SI) for 3 years = 100 : (300 + 75)
⇒ (CI – SI) for 2 years : (CI – SI) for 3 years = 100 : 375 = 4 : 15
∴ Required ratio is 4 : 15
