Question : The pie chart given below shows the number of cars sold by 8 different companies. The total number of cars sold by all these 8 companies is 5,000. The number of cars sold by a particular company is shown as a percentage of the total number of cars sold by all these 8 companies. What is the ratio of the total central angle formed by sectors R and S to the total central angle formed by sectors U and V?
Option 1: 1 : 4
Option 2: 2 : 1
Option 3: 1 : 2
Option 4: 3 : 1

Question : What is the reflection of the point (5, – 2) in the line $x$ = – 1?
Option 1: (– 7, – 2)
Option 2: (5, 0)
Option 3: (7, – 2)
Option 4: (5, 2)
Correct Answer: (– 7, – 2)
Solution : Given: The point (5, –2) in the line $x = – 1$. The following formula, $(2c–x, y)$ is used to find the value of $c = – 1$. So, the reflection point is $(2c–x, y)$ i.e. $(2×(– 1) – 5, – 2)$.
Question : Directions: Select the correct mirror image from the following options, when the mirror is placed on the right side of the given figure.
