Question 61

A number X is 60% of the average of 20, 28 and 36. What is the value of the number X?

Solution

A number X is 60% of the average of 20, 28 and 36.

X = 60% of $$\frac{(20+28+36)}{3}$$

X = 60% of $$\frac{84}{3}$$

X = 60% of 28

X = $$\frac{60}{100}\times28$$

= 16.8

Value of the number X = 16.8
