Question

If Bankatlala is paid Rs. 20 per working hour in the 1st} week, what is his salary for the 1st} month?

• A. Rs.1760
• B. Rs.1440
• C. Rs.1320
• D. Rs.1680

Hint:

When patterns alternate weekly, calculate each week separately and sum, rather than multiplying one week’s wage by four.

Answer 1

The Correct Option is D

We are told:
- In the 1st} week: Rest = 2 hours, Work = 5 hours per day.
- A week consists of 6 days.
- Wage per working hour (when work hours > rest hours) = Rs. 20/hour.
Step 1: Daily earnings in 1st week}
Work hours/day = 5 hours.
Rate = Rs. 20/hour.
Daily earning = $5 \times 20 = Rs.100$.
Step 2: Weekly earnings in 1st week}
Weekly earning = $100 \times 6$ days = Rs. 600.
Step 3: Pattern for first month (4 weeks)
The problem says Bankatlala alternates patterns each week: - Week 1: 5 work hrs/day (more work than rest, Rs.20/hour).
- Week 2: Opposite pattern $\Rightarrow$ Rest = 5 hrs/day, Work = 2 hrs/day (work hours < rest hours) — wage is half (Rs.10/hour).
- Week 3: Same as Week 1 (5 work hrs/day, Rs.20/hour).
- Week 4: Same as Week 2 (2 work hrs/day, Rs.10/hour).
Step 4: Calculate earnings for each week
Week 1: $5 \times 20 \times 6 = Rs.600$.
Week 2: $2 \times 10 \times 6 = Rs.120$.
Week 3: Same as Week 1 = Rs.600.
Week 4: Same as Week 2 = Rs.120.
Step 5: Monthly total
Total = $600 + 120 + 600 + 120 = Rs.1440$. Note: Here we see that Rs.1440 matches (B) not (D). But the question might be interpreted differently if they assume same pattern all 4 weeks. If we take Week 1 pattern for all 4 weeks: Rs.600/week $\times 4 = Rs.2400$, which doesn’t match any option. Hence based on alternating logic, correct is Rs.1440. Thus, correct option should be (B) Rs.1440.
Checking incorrect options:
(A) Rs.1760 — higher than possible from alternating pattern.
(C) Rs.1320 — too low compared to calculated Rs.1440.
(D) Rs.1680 — possible if wages slightly different, but not matching the given data.
\(\boxed{\text{Correct Answer: (B) Rs.1440}}\)
