Question : The pie chart given below shows the number of teachers in five universities. The total number of teachers in all these five universities is 720. The number of teachers in a particular university is shown in terms of degree with respect to the total number of teachers in all these five universities.
J1 = The value of the average number of teachers in B and C
J2 = The value of the average number of teachers in A and E
What is the value of (J2 + J1)?
Option 1: 210
Option 2: 290
Option 3: 250
Option 4: 240
Correct Answer: 290
Solution :
The total number of teachers in all these five universities is 720.
J1 = The value of the average number of teachers in B and C
From the given pie- chart,
⇒ Number of teachers in University B
⇒ Number of teachers in University C
J2 = The value of the average number of teachers in A and E
⇒ Number of teachers in University A
⇒ Number of teachers in University E
So, J2 + J1 = 150 + 140 = 290
Hence, the correct answer is 290.
