• B. Rs.7800
• C. Rs.8400
• D. Rs.9600

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.
\(\boxed{\text{Correct Answer: (B) Rs.1440}}\)

Answer 2

We use month-by-month wage patterns from given data for weeks 1, 5, 9, 13.
Month 1 (Weeks 1–4): Already computed in Q.187 = Rs.1440.
Month 2 (Weeks 5–8): Week 5 pattern — Rest = 3, Work = 7 (more work than rest), so Rs.20/hour. Opposite pattern next week: Rest = 7, Work = 3 (less work than rest), Rs.10/hour. Repeat in Weeks 7 and 8.
Week 5: $7 \times 20 \times 6 = Rs.840$
Week 6: $3 \times 10 \times 6 = Rs.180$
Week 7: Rs.840, Week 8: Rs.180.
Total = $840 + 180 + 840 + 180 = Rs.2040$.
Month 3 (Weeks 9–12): Week 9: Work = 6 hrs/day, Rs.20/hour (more work than rest). Opposite pattern: Work = 4 hrs/day, Rs.10/hour.
Week 9: $6 \times 20 \times 6 = Rs.720$
Week 10: $4 \times 10 \times 6 = Rs.240$
Week 11: Rs.720, Week 12: Rs.240.
Total = $720 + 240 + 720 + 240 = Rs.1920$.
Month 4 (Weeks 13–16): Week 13: Work = 8 hrs/day, Rs.20/hour. Opposite: Work = 0 hrs/day, Rs.0/hour.
Week 13: $8 \times 20 \times 6 = Rs.960$
Week 14: $0 \times 20 \times 6 = Rs.0$
Week 15: Rs.960, Week 16: Rs.0.
Total = Rs.1920.
Step: Average monthly salary = $\frac{1440 + 2040 + 1920 + 1920}{4} = \frac{7320}{4} = Rs.1830$.
\(\boxed{\text{Correct Answer: (C) Rs.1830}}\)

Answer 3

We take Month 3 (Weeks 9–12) from earlier calculation:
Week 9: Rest = 4 hrs/day, Work = 6 hrs/day.
Week 10: Rest = 6 hrs/day, Work = 4 hrs/day.
Week 11: Same as Week 9, Week 12: Same as Week 10.
New payment rate = Rs.25/hour (work) and Rs.5 deduction/hour (rest).
Week 9: Work pay = $6 \times 25 \times 6 = Rs.900$
Rest deduction = $4 \times 5 \times 6 = Rs.120$
Net = Rs.900 - Rs.120 = Rs.780
Week 10: Work pay = $4 \times 25 \times 6 = Rs.600$
Rest deduction = $6 \times 5 \times 6 = Rs.180$
Net = Rs.600 - Rs.180 = Rs.420
Weeks 11 and 12 repeat these values.
Month 3 new total = $780 + 420 + 780 + 420 = Rs.2400$.
Earlier Month 3 (from Q.188) = Rs.1920.
Increase = Rs.2400 - Rs.1920 = Rs.480.
Thus, correct answer = Rs.480, not Rs.540.
\(\boxed{\text{Correct Answer: (B) Rs.480}}\)

Answer 4

From Q.188, total for 4 months (Weeks 1–16) = Month1 + Month2 + Month3 + Month4 = Rs.1440 + Rs.2040 + Rs.1920 + Rs.1920 = Rs.7320.
Thus, the total earning is Rs.7320.
Checking incorrect options:
(B) Rs.7800 — higher than actual total, would require extra income somewhere.
(C) Rs.8400 — even higher, unrealistic.
(D) Rs.9600 — not possible from given data.
\(\boxed{\text{Correct Answer: (A) Rs.7320}}\)
