In a factory, workers work in three shifts, say shift 1 , shit 2 and shift 3 and they get wages in the ratio 3 : 4 : 8 depending on the shift 1 , 2 and 3 respectively. Number of workers in the shifts are in the ratio 3 : 2 : 5. If the total number of workers working is 1500 and wages per worker in shift 1 is Rs . 300 , then the mean wage of a worker is

Options

  1. ARs .   460
  2. BRs .   520
  3. CRs .   570
  4. DRs .   420

Correct answer

C. Rs .   570

Step-by-step solution

Workers in 1 s t shift = 450 Wages in 1 s t shift = Rs . 300 Workers in 2 n d shift = 300 Wages in 2 n d shift = Rs .   400 Workers in 3 r d shift = 800 M e a n = 450 × 300 + 300 × 400 + 750 × 800 1500 = 90 + 80 + 400 = 570 Mean wage = Rs . 570
