Question : The given chart shows the marks scored by a class X student in different subjects.
If the total marks are 1800, then find the difference between the marks scored in science and mathematics.
Option 1: 2
Option 2: 10
Option 3: 1
Option 4: 5
Correct Answer: 10
Solution :
As per the given graph,
The total mark is 1800.
The total degree of marks = 360°
The total marks scored in Science = $\frac{82^\circ}{360^\circ}$ × 1800 = 410
The total marks scored in Mathematics = $\frac{84^\circ}{360^\circ}$ × 1800 = 420
$\therefore$ The required difference = 420 – 410 = 10
Hence, the correct answer is 10.
