Question : A car can cover a certain distance in $4\frac{1}{2}$ hours. If the speed increases by 5 km/hr, it would take $\frac{1}{2}$ hour less to cover the same distance. Find the slower speed of the car.
Option 1: 50 km/hr
Option 2: 40 km/hr
Option 3: 45 km/hr
Option 4: 60 km/hr
Correct Answer: 40 km/hr
Solution : Ratio of time = $\frac{9}{2}:(\frac{9}{2}-\frac{1}{2})=\frac{9}{2}:4=9:8$ Ratio of speed = 8 : 9 Let the slower speed be 8k and the increased speed be 9k. The speed of the car increased by 5 km/hr. So, 9k – 8k = 5 ⇒ k = 5 $\therefore$
Question : A person deposited INR 15,600 in a fixed deposit at 10% per annum simple interest. After every second year, he adds his interest earned to the principal. The interest at the end of 4 years is:

Question : Directions: Select the number that is related to the third number in the same way as the second number is related to the first number. 12 : 36 :: 18 : ?
Option 1: 64
Option 2: 48
Option 3: 83
Option 4: 81
Correct Answer: 81
Solution : Given: 12 : 36 :: 18 : ?
