Answer: C) Both A & B Explanation: The given number puzzle can be soved in two ways. Logic 1 :: Row 1 - 2 x 3 = 6 , 6 x 3 = 18 Row 2 - 4 x 5 = 20 , 20 x 5 = 100 Row 3 - 3 x 7 = 21 , 21 x 7 = 147 Hence, the missing number could be 3. Logic 2 :: Row 1 - 6 x (2+1) = 18 Row 2 - 20 x (4+1) = 100 Row 3 - 21 x (6+1) = 147 Hence, the missing number could be 6. Therefore, 3 or 6 is the right answer.

Answer : 3. "4 days"
Explanation :
Answer: C) 4 days Explanation: One day work of 6 boys and 8 girls is given as 6b + 8g = 1/10 -------->(I) One day work of 26 boys and 48 women is given as 26b + 48w = 1/2 -------->(II) Divide both sides by 2 in (I) and then multiply both sides by 5 Now we get, 15b + 20g = 1/4. Therefore, 15 boys and 20 girls can do the same work in 4 days.
