Q:

# In a class of 180, where girls are twice the number of boys, Rupesh[a boy]  ranked 34th from the top. If there are 18 girls ahead of Rupesh, how many boys are after him in rank?

 A) 45 B) 44 C) 60 D) can't be determined

Explanation:

No. of boys upto the 34th rank = 34-18 = 16

Total no of boys = $\inline \frac{180}{2+1}\times 1= 60$

$\inline \therefore$ number of boys after the rank of Rupesh = 60 - 16 = 44

Q:

Vishal is 24th from either end of the row of boys ? How many boys are there in the row ?

Q:

If it is possible to form a number with the second, the fifth and the eighth digits of the number 31549786, which is the perfect square of a two - digit even number, which of the following will be the second digit of that even number ?

 A) 1 B) 4 C) 6 D) None of these

Explanation:

The 2nd, 5th and 8th digits of the number 31549786 are 1, 9 and 6 respectively.

The perfect square of a two - digit even number, formed using the digits 1, 9 and 6 is 196. And, $\inline 196 = 14^{2}$

So, the required even number is 14. Clearly, its second digit is 4.

Hence, the answer is (b).
