Answer 1

Answer:

144

Step-by-step explanation:

sum of 5 member=150*5 =750

sum of height of 4 member =150+151+152+153=606

height of 5th member=750-606=144

Answer 2

Given - Average height

Find - Height of the fifth person

Solution - The height of the fifth person is 144 centimetres.

Average is calculated by the formula= sum of all the quantities/total number of quantities

Let the height of the fifth person be x.

Sum of all quantities of height = 153 + 150 + 151 + 152 + x

Sum of all quantities of height = 606 + x

Total number of quantities = 5

Keep the values in the formula to find the height of the fifth person.

150 = (606 + x)/5

150*5 = 606 + x

750 - 606 = x

x = 144 centimetres.

Thus, the height of the fifth person is 144 centimetres.
