Option 1: 2 : 1
Option 2: 17 : 14
Option 3: 11 : 10
Option 4: 11 : 7
Correct Answer: 11 : 7
Solution :
The number of worker in the factory whose daily wages are below Rs. 600
= 40 + 50 + 58 + 72
= 220
The number of worker in the factory whose daily wages are more Rs. 650
= 55 + 48 + 37
= 140
Required ratio= 220 : 140 = 11 : 7
Hence the ratio is 11 : 7.
