Question

(2 7 5 4 3 9 6 2 4 9 5 4 8 2 6 3)
In the above number sequence, how many pairs of adjacent numbers are there whose product is 12?
A. One
B. Two
C. Three
D. Four

Answer 1

Hint- In order to solve this type of question, firstly we must know the meaning of adjacent numbers i.e adjacent numbers are those numbers which are next to each other.Then take the product of every 2 digits. Thus get our desired answer.

Complete step-by-step answer:
Adjacent numbers are those numbers which are next to each other.
So we must take the product of every 2 digits given above to get the right answer.
From the above sequence, there are only three pairs whose product is 12
 $ \Rightarrow $ 4$ \times $ 3
 $ \Rightarrow $ 6$ \times $ 2
 $ \Rightarrow $ 2$ \times $ 6
$\therefore $ option c is correct.

Note-To solve this question, the easiest way is take every pair and check whether the pair satisfies the desired condition or not. This will ensure the right answer with proper clearance. Thus we will get our desired answer.
