Correct Answer: 25
Solution : Given: (15, 13, 10, 2) (20, 5, 4, 11) (13, 8, 13, 6) (7, 6, 2, ?)
The sum of the numbers of each set is equal to 40. (15, 13, 10, 2) = 15 + 13 + 10 + 2 = 40 (20, 5, 4, 11) = 20 + 5 + 4 + 11 = 40 (13, 8, 13, 6) = 13 + 8 + 13 + 6 = 40 Similarly, (7, 6, 2, ?) = 7 + 6 + 2 + ? = 40 (Let the missing number be a.) ⇒ 15 + a = 40 ⇒ a = 40 – 15 ⇒ a = 25
So, the required number is 25. Hence, the second option is correct.
