On reducing the fraction, we get
It is shown that the number of cats is reduced to 20.
So, let the number of dogs after sometime be x
Thus,
After cross multiplying we get:
140 = 4x
x = 35

A. 27 ⇒ The point value is known, so there is no variable.
B. X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by
or divided by 2 to get half the speed of the car.
C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.
