Answer 1

Answer:

285

Step-by-step explanation:

50, ` 55, ` 60, ` 58, ` 59, ` 72, ` 65, ` 68, ` 53, ` 50, ` 67, ` 58,  ` 63, ` 69, ` 74, ` 63, ` 61, ` 57, ` 62, ` 64.

50 - 55      3     ( 50 , 50 , 53)

55 - 60      5     (55 , 57 , 58 , 58  , 59)

60 - 65      6    (60 , 61 , 62 , 63 , 63 , 64)

65 - 70      4    ( 65 , 67 , 68 , 69)

70 - 75       2   ( 72 , 74)

Bonus paid = 3 * 100  + 5 * 200  + 6 * 300  + 4 * 400 + 2 * 500

= 300 + 1000 + 1800 + 1600 + 1000

= 5700

the average bonus paid per wage earner = 5700/20  =  285
