Question

Given below is the table of the marks of 10 students. For getting promoted to section A, a student has to score more marks than the average. Can you tell me from the given options, which student will not be promoted to Section A?​

$\begin{array}{cccc}\text{Name}& \text{Marks}& \text{Name}& \text{Marks}\\ \text{Pavani}& 79& \text{Ajit}& 77\\ \text{Goutham}& 81& \text{Kushagra}& 73\\ \text{Deepthi}& 68& \text{Manish}& 94\\ \text{Pavan}& 85& \text{Satyam}& 81\\ \text{Akash}& 62& \text{Sarosh}& 80\end{array}$

• A. Pavani
• B. Sarosh
• C. Deepthi
• D. Goutham

Answer 1

The correct option is C

Deepthi

We know that,

$Average=\frac{Sumofallobservations}{Totalnumberofobservations}$​​

Average marks=$\frac{79+81+68+85+62+77+73+94+81+80}{10}$=$\frac{780}{10}$=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.
