The average height of 22 toddlers increases by 2 inches when two of them leave this group. If the average height of these two toddlers is one-third the average height of the original 22, then the average height, in inches, of the remaining 20 toddlers is

- 30
- 28
- 32
- 26

### Answer

Let the average height of the 20 toddlers be x inches. When the 2 toddlers are included, the average of the group comes down by 2, i.e. it becomes x – 2.

Also, given, that the average height of the 2 toddlers is one-third of the average height of the 22 toddlers, x – 2.

20(x) + 2(x - 2)/3 = (x - 2) × 22

Upon solving,

x = 32 inches.

**The correct option is C.**
