Worker is paid Rs.20 per day worked and forfeits Rs.3 per idle day. In 60 days he got Rs.280. Idle days:
A15
B20
C40
D30
Answer & Solution
Correct answer: C. 40
1. Let idle days = i. Worked days = 60 − i.
2. 20(60−i) − 3i = 280 → 1200 − 20i − 3i = 280 → 23i = 920.
3. i = 920/23 = 40. So 40 days idle.
