Question : Two trains 121 m and 99 m in length, respectively, are running in opposite directions, one at a speed of 40 km/hr and the other at a speed of 32 km/hr. At what time will they be completely clear of each other from the moment they meet?
Option 1: 11 sec
Option 2: 12 sec
Option 3: 13 sec
Option 4: 10 sec
Correct Answer: 11 sec

Question : In triangle ABC, the bisector of angle BAC cuts the side BC at D. If AB = 10 cm, and AC = 14 cm then what is BD : BC ?
Option 1: 5 : 3
Option 2: 7 : 5
Option 3: 5 : 2
Option 4: 5 : 7
Correct Answer: 5 : 7
Solution : The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle. According to the concept, $\frac{AB}{AC} = \frac{BD}{DC}$ ⇒ $\frac{10}{14} = \frac{BD}{DC}$ ⇒ $\frac{5}{7} = \frac{BD}{DC}$ $\therefore BD:DC=5:7$ Hence, the correct answer
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits.
