Question

The age of the labourers working in factory in years is as follows:

31, 41, 28, 54, 34, 27, 23, 33, 35, 42. Range of their age is

1. 31 years
2. 35 years
3. 23 years
4. 20 years

Answer 1

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.
