Question

Study the given pattern carefully and select the number that can replace the question mark (?) in it?

\(\begin{array}{*{20}{c}} {16}&{36}&{81}\\ {50}&{42}&{60}\\ {29}&{27}&? \end{array}\)

1. 39
2. 37
3. 21
4. 25

Answer 1

Correct Answer - Option 1 : 39

The logic follows here is :

Column wise :

Third term = (√ First term) + (Second term ÷ 2)

First Column → 16, 50, 29

(√16) + (50 ÷ 2) = 4 + 25 = 29.

Second Column → 36, 42, 27 

(√36) + (42 ÷ 2) = 6 + 21 = 27.

Third Column → 81, 60, ?

? = (√81) + (60 ÷ 2) = 9 + 30 = 39.

Hence, the correct answer is "39".
