The pie chart given below shows the salary given by a company to its seven employees. The total salary given by the company to all its employees is ₹7,20,000. The salary spent on a particular employee is shown in terms of degrees with respect to the total salary spent on all seven employees. J1 = Value of total salary given to Q, R and S
J2 = Value of total salary given to T, U and V
J3 = Value of difference of salary of Q and R
What is the value of (J2 − J1 − J3)?
- A.
₹4,20,000
- B.
₹3,20,000
- C.
₹2,20,000
- D.
₹2,30,000

Show answer & explanation
Correct answer: C
Key idea: convert each degree of the pie chart to rupees and compute the required group sums and difference.
Convert degrees to rupees: each degree = ₹7,20,000 ÷ 360 = ₹2,000.
Compute J1 (total for Q, R, S): angles 48° + 16° + 36° = 100° → J1 = 100 × 2,000 = ₹2,00,000.
Compute J2 (total for T, U, V): angles 72° + 108° + 62° = 242° → J2 = 242 × 2,000 = ₹4,84,000.
Compute J3 (difference between Q and R): |48° − 16°| = 32° → J3 = 32 × 2,000 = ₹64,000.
Now calculate J2 − J1 − J3 = ₹4,84,000 − ₹2,00,000 − ₹64,000 = ₹2,20,000.
Final answer: ₹2,20,000
