The following pie chart represents the percentage-wise break up of research scholars in terms of their specialisation in Ph.D. in Physics. Total number of research scholars is 8000. Study the pie chart carefully and answer the question given below:

The number of research scholars having Meteorology as their specialisation is approximately (correct up to two decimal places) what per cent of the number of research scholars with Astrophysics specialisation?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 73.91%.
According to the given pie-chart,
Number of research scholars with Meterology as specialisation = 17% of 8000 = 1360
Number of research scholars with Astrophysics as specialisation = 23% of 8000 = 1840
Required percentage = (1360/1840) × 100
⇒ 73.91%
