Answer 1

Correct Answer - Option 4 : 72.5

Concept used:

Percentage 

Calculation:

Total no of workers = 4 +10 + 20 + 40 + 50 

Total no of workers = 124

Workers earning more than Rs.70

⇒ 50 + 40 = 90

Percentage of workers earning more than Rs.70 

⇒ \(\frac{{90}}{{124}} \times 100\)

∴ 72.5%
