Question 38

In the following question, select the letter which can be placed at the sign of question mark (?) from the given alternatives.

Solution

In each row, number at the end is twice the sum of remaining numbers.

Eg :- $$(5+7+6)\times2=18\times2=36$$

and $$(9+11+8)\times2=28\times2=56$$

Similarly, $$(10+x+17)\times2=64$$

=> $$27+x=\frac{64}{2}=32$$

=> $$x=32-27=5$$

=> Ans - (A)
