Q22
A certain amount of money was divided among Pinu, Meena, Rinu and Seema. Pinu received 20% of the total amount and Meena received 40% of the remaining amount. If Seema received 20% less than Pinu, the ratio of the amounts received by Pinu and Rinu is
Answer: B
Key idea: Take the total as 100 and work through each share.
- Pinu \(= 20\% \text{ of } 100 = 20\); remaining \(= 80\).
- Meena \(= 40\% \text{ of } 80 = 32\).
- Seema \(= 20\%\) less than Pinu \(= 0.8 \times 20 = 16\).
- Rinu \(= 100 - 20 - 32 - 16 = 32\).
Pinu : Rinu \(= 20 : 32 = 5 : 8\).
Hence, the answer is (B) 5 : 8.
