Question

In the given series
$5,6,8,2,5,5,2,5,4,2,8,5,3,5,2,8,6,8,2,5,2,8,6,2,8,5,7,2,8$
how many times the number ${}^{\prime }{2}^{\prime }$ has come before $8$ and $5$ has not come after $8$?

• A. $4$
• B. $3$
• C. $2$
• D. $1$

Answer 1

Answer: (B)

$3$

In the given series, 2 has come 5 times before 8. But 2 times 5 comes after 8.

So, total 3 times 2 has come before 8 and 5 has not come after 8.

Hence, option B is correct.
