# Find Out the New Average Height.

Six friends have an average height of 167 cms. A boy with height 162 cm leaves the group. Find the new average height.

- 167 cm
- 168 cm
- 169 cm
- 166 cm

**Answer: (2) 168 cm**

**Explanation:-
**The average of height of six friends = 167 cm

Then, the sum of the ages of six friends = 6 x 167

= 1002 cm

A boy with height 162 cm leaves the group,

Then, the sum of remaining 5 friends = 1002 – 162

= 840 cm

Now, the new average of height = 840/5

= 168 cm

Hence, the answer is (2) 168 cm.
