Correct Answer: 3600
Solution :
Given: The number of males in the S department = 1080.
⇒ $54^{\circ}=1080$
⇒ $1^{\circ}=20$
The number of males in the T department is $90^{\circ}$.
= 90 × 20 = 1800
The number of males in the P department is $30^{\circ}$.
= 30 × 20 = 600
The number of males in the Q department is $90^{\circ}$.
= 90 × 20 = 1800
J = Total number of males in T and P departments = 1800 + 600 = 2400.
K = Difference between the number of males in P and Q departments = 1800 – 600 = 1200
The value of J + K = 2400 + 1200 = 3600
Hence, the correct answer is 3600.
