Question

2. Simran scored 89 as the average of 7 subjects. What is the total marks scored by her?​

Answer 1

Answer:

89 ×7

Step-by-step explanation:

The mean is 89

as we don't know the total marks we will assign a variable 'x'

now by the average formula we know that average = x/7 ( denominator is 7 as there are 7 subjects)

and we have the equation x/7 = 89

so x = 89 ×7 ( by transposition method)

so overall x is 623

so the total marks secured by simran is 623.
