Question : The average age of eight girls is y years. 5 new girls having ages (in years) given by y + 3, y – 6, y + 15, y + 8, and y + 6 join the class. What is the new average age of the class?
Option 1: (y + 2) years
Option 2: (y + 6) years
Option 3: (y + 3) years

Question : A student goes to school at the rate of $\frac{5}{2}$ km/hr and reaches 6 minutes late. If he travels at the speed of 3 km/hr, he reaches 10 minutes earlier. The distance from the school is:
Option 1: 45 km
Option 2: 20 km
Option 3: 10 km
Option 4: 4 km
Correct Answer: 4 km
Solution : Let the distance from the school be $x$ km. According to the question, $\frac{x}{\frac{5}{2}}-\frac{x}{3}=\frac{6+10}{60}$ ⇒ $\frac{2x}{5}-\frac{x}{3}=\frac{16}{60}$ ⇒ $6x-5x=\frac{16}{60}×15$ $\therefore x=4$ km Hence, the correct answer is 4 km.
