Question 17

In the following question, select the missing number from the given series

Solution

The pattern followed is that in each row the number at the end is the square root of the product of first two.

Eg :- $$\sqrt{25\times144}=\sqrt{5\times5\times12\times12}=5\times12=60$$

$$\sqrt{81\times225}=\sqrt{9\times9\times15\times15}=9\times15=225$$

Similarly, $$\sqrt{49\times289}=\sqrt{7\times7\times17\times17}=7\times17=119$$
