Answer: 6 days
Explanation Work done by 12 children in 16 days = 1 (full work) Work done by 1 child in 16 days = 1/12 Work done by 1 child in 1 day = 1/(12 × 16) = 1/192 Work done by 8 adults in 12 days = 1 Work done by 1 adult in 12 days = 1/8 Work done by 1 adult in 1 day = 1/(8 × 12) = 1/96 Work done by 16 adults in 3 days = 16 × 3 × (1/96) = 1/2 Remaining work = 1 - 1/2 = 1/2 Now, 6 adults and 4 children work together: Work done by 6 adults in 1 day = 6 × 1/96 = 6/96 = 1/16 Work done by 4 children in 1 day = 4 × 1/192 = 4/192 = 1/48 Total work done per day = (1/16 + 1/48) = (3 + 1)/48 = 4/48 = 1/12 Days required = (1/2) ÷ (1/12) = 6 days
Answer: 285
Explanation If a month starts with Sunday, then the number of Sundays in that month is 5 The remaining days is 3 0 − 5 = 2 5 Given that average number of visitors on Sundays is 5 1 0 Therefore, 5 1 0 = 5 sum of the number of visitors on Sundays ⟹ sum of the number of visitors on Sundays = 5 1 0 × 5 = 2 5 5 0 -----(1) Given that average number of visitors on other days is 2 4 0 Therefore, 2 4 0 = 2 5 sum of the number of visitors on other days ⟹ sum of the number of visitors on other days = 2 4 0 × 2 5 = 6 0 0 0 -----(2) Total average is 3 0 total number of visitors = 3 0 2 5 5 0 + 6 0 0 0 = 3 0 8 5 5 0 = 2 8 5 Therefore, the average number of visitors per day in a month of 30 days beginning with a Sunday is 2 8 5 .

Answer: 16
Explanation Given the series is: 1, 2, 2, 4, 4, 6, 8, 8, 16 Let's break it down: Powers of 2 are interspersed with repetitions: 1 (2^0), 2 (2^1), 2, 4 (2^2), 4, 8 (2^3), 8, 16 (2^4) If the pattern continues with repetitions after powers of 2: The next number would logically be 16 (a repetition of the last number, 16).
