Question

The mean of 5 numbers is 7.
The numbers are in the ratio 1 : 1 : 1 : 2 : 2.
Find the numbers.

Answer 1

Step-by-step explanation:

mean = total sum of observations/total observations

so total sum = 7X ( take x as variable in the ratio )

so 7 = 7x/5

so x = 5

therefore no. = 5,5,5,10,10
