total earnings from ‘commerce' is twice that from 'transportation',
To Find : ratio of average wages in these occupations
A) 16:23
B) 23:16
C) 5:4
D) 23:8
Solution:
average wages in commerce = x
Commerce = 115°
average wages in transportation= y
Transportation = 40°
total earnings from ‘commerce' is twice that from 'transportation',
=> 115 * x = 2 ( 40 * y)
=> x / y = 80 / 115
=> x/y = 16 / 23
=> x : y = 16 : 23
ratio of average wages in commerce : transportation = 16 : 23
