Question : Study the given table carefully and answer the following question.
The table shows the percentage of students in four departments - Mechanical, Civil, Computer Science, and Applied - with each student being in only one department. The table also shows the number of students in these four departments in five different colleges, with the total number of students being 2080.
If the number of students in IIT Bombay is 20% less than the number of students in IIT Madras, the number of students in IIT Bombay is:
Option 1: 300
Option 2: 500
Option 3: 200
Option 4: 400
Correct Answer: 400
Solution :
Given: Total students = 2080
Students in IIT Bombay and IIT Madras = Total students – Rest of the IITs
= 2080 – 430 – 350 – 400 = 900
The number of students in IIT Bombay is 20% less than the number of students in IIT Madras.
Let the number of students in IIT Madras be 100$x$. Then, the number of students in IIT Bombay = 80$x$.
So, 100$x$ + 80$x$ = 900
⇒ 180$x$ = 900
⇒ $x$ = 5
Number of students in IIT Bombay = 80 × 5 = 400
Hence, the correct answer is 400.
