Solution

The correct option is C

Deepthi


We know that,

Average=Sum of all observationsTotal number of observations​​

Average marks = 79+81+68+85+62+77+73+94+81+8010 = 78010 = 78.

Students who scored less marks than the average, won't be promoted to section A. So, from the given options, only Deepthi has lesser marks than 78.
