Question 44

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

Solution

The logic here is

$$\frac{5\times6}{2}=\frac{30}{2}=15$$

$$\frac{4\times9}{2}=\frac{36}{2}=18$$

The top number is equal to the half of the product of the bottom numbers.

Similarly,

The required number = $$\frac{6\times7}{2}=\frac{42}{2}=21$$

Hence, the correct answer is Option C
