In an examination, the marks scored by Arjun, Ajay, and Anil are in the ratio 2 : 4 : 9. If Arjun secured 30 marks, how many marks did Ajay and Anil score?

1. Ajay = 40, Anil = 90
2. Ajay = 60, Anil = 135
3. Ajay = 120, Anil = 180
4. Ajay = 90, Anil = 40

Correct answer: Ajay = 60, Anil = 135

Solution

Since the ratio is 2:4:9 and Arjun's share (2 parts) equals 30, one part = 15. Ajay's share = 4 x 15 = 60 and Anil's share = 9 x 15 = 135.
