Question 13
Study the given pattern carefully and select the number that can replace the question mark (?)in it.
Solution
The pattern follows column Rule
$$(48 - 28) \times 3 = 20 t\times 3 = 60$$
$$ (71 - 65) \times 18 = 6 \times 18 = 108 $$
Next $$ (35 - ?) \times 7 = 98 $$
$$\Rightarrow 35\times 7 - 7? = 98 $$
$$\Rightarrow 245 - 7 ? = 98 $$
$$\Rightarrow -7? = 98-245 $$
$$\Rightarrow 7 ? = 147 $$
$$\Rightarrow ? = 21 $$ Ans
