Question 16

Select the missing numbers from the given alternatives

Solution

In each row, the number in the middle is the arithmetic mean of the other two.

Eg = $$\frac{110+90}{2}=\frac{200}{2}=100$$

and $$\frac{80+40}{2}=\frac{120}{2}=60$$

Similarly, $$\frac{150+x}{2}=120$$

=> $$150+x=240$$

=> $$x=240-150=90$$

=> Ans - (D)
