Question

If the minimum value in a set is $15$ and its range is $55$, the maximum value of the set is _______.

• A. $40$
• B. $60$
• C. $80$
• D. $70$

Answer 1

The correct option is D $70$

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.

Range = 55

In the given series, H= x and L= 15

Range => x-15 = 55

=> x = 55+15 = 70
