A) 14.4 sec	B) 15.5 sec
C) 18.8 sec	D) 20.2 sec

Answer & Explanation Answer: A) 14.4 sec

Explanation:

Let the length of the train be L metres

Speed of first train = $\frac{3600}{18} x L$ m/hour

Speed of secxond train = $\frac{3600}{12} x L$ m/hour

When running in opposite directions, relative speed = 200 L + 300 L m/hour

Distance to be covered = L + L = 2L metre

Time taken = $\frac{2 L}{500 L} x 3600$ sec

=14.4 sec

Q:

5/9 of the part of the population in a village are females. If 30 % of the females are married. The percentage of unmarried males in the total males is ?

A) 62.5 %	B) 125 %
C) 84.32 %	D) 46.87 %

Answer & Explanation Answer: A) 62.5 %

Explanation:

Let total population = p
number of females = 5p/9
number of males =(p-5p/9) = 4p/9
married females = 30% of 5p/9 = 30x5p/100x9 = p/6
married males = p/6
unmarried males =(4p/9-p/6) = 5p/18
Percentage of unmarried males in the total males = {(5p/18)/4p/9}x100 = (5p/18)x(9/4p) = 125/2 % = 62.5%
