Question

the average height of 5 pupils in a class is 140cm.if the total height of 4pupils is 590 cm, find the height of the fifth pupil.​

Answer 1

Answer:

Let the height of fifth person be X

Average height=Total Height/Number of puplis.

The total height of four pupils=590.

That is, 590+X÷5=140

590+X/5=140/1

590+X=140×5

590+X=700

X=700-590

X=110

Therefore height of the fifth pupil, X=110cm.

HOPE THIS HELPS YOU DEAR..
