Best answer
Correct Answer - Option 1 : 31 years

Concept:

Range = Highest value - Lowest value

Calculation:

On arranging the age of the laborers working in the factory in ascending order, we get

23, 27, 28, 31, 33, 34, 35, 41, 42, 54

⇒ Highest value = 54

Also, Lowest value = 23

∴ Range = 54 - 23 = 31

Hence, the range of their age is 31 years.
