Answer 2

Average= sum of observations/number of observations

Sum of observation= average ×number of observations

Given:

average of 3 no.=36
average of 2 of no.= 48.

Sum of 3 numbers=36×3= 108

Sum of 2 numbers= 48 × 2= 96

Third number= sum of three numbers - sum of two numbers

Third Number= 108 - 96

Third Number= 12
