Question

In an examination, a candidate scores the following percentage of marks :
English -44; Hindi -58; Maths -74;Physics -61; Chemistry -62. Ifweights 2, 4, 4, 5, 3 respectively allotted to these subjects, then the candidate's weighted mean percentage is

• A. 61
• B. 61.5
• C. 62
• D. 62.5

Answer 1

The correct option is B 61.5

Let the weighted mean percentage of the candidate be $M$ then

$M=\frac{2\times 44+4\times 58+4\times 74+5\times 61+3\times 62}{2+4+4+5+3}$

$M=61.5$

Hence, this is the required answer.
