Question

Average marks of a candidate in 6 subjects are 52. His marks in 5 subjects are 60, 48,36,55 and 51. Find his marks in 6th subject.

Answer 1

Answer:

If 52 is the average marks in 6 subjects of a candidate and his marks are 60,48,36,55 and 51, then his marks in the 6 th subject is 62

Step-by-step explanation:

Given

Average mark of the candidate = 52

Number of subjects = 6

Average mark = sum of marks in 6 subjects / 6

Let A be the sixth subject. Then,

$52=\frac{60+48+36+55+51+A}{6} \\\\52*6 = 250+ A\\\\312 = 250 + A\\\\A= 312-250\\\\A= 62$

So marks in the 6 th subject is 62
