In a group of 60 workers, the average monthly income per worker is ₹28,000. If 20 junior workers average ₹18,000 each, what is the average monthly income of the senior workers?

1. ₹33,000
2. ₹34,500
3. ₹35,000
4. ₹36,500

Correct answer: ₹33,000

Solution

Total income of 60 workers = \(60 \times 28000 = 16,80,000\). Income of 20 junior workers = \(20 \times 18000 = 3,60,000\). So income of 40 senior workers = \(16,80,000 - 3,60,000 = 13,20,000\), and their average = \(13,20,000/40 = 33,000\).
