Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 400.
Given that,
The average monthly salary of workers in a factory is ₹6,000
The average monthly salary of 100 technicians is ₹12,000
The average monthly salary of non-technicians is ₹4,000
Let the number of workers be P
According to the question
⇒ 6000 P = 12000 × 100 + 4000 × (P - 100)
⇒ 6000 P - 4000 P = 1200000 - 400000
⇒ 2000 P = 800000
⇒ P = 400
