The Mean of 10 Numbers is 58. if one of the number is 40. than what is the Mean of other 9 numbers??​

Answer»

ong>Answer:

60

Explanation:

The FORMULA for calculating mean is-

(SUM of NUMBERS)/(no. of numbers)

Given, mean of 10 numbers is 58. So,

(N1+N2+N3+N4+ N5+N6+N7+N8+N9+ N10)/10 = 58

(N1+N2+N3+N4+ N5+N6+N7+N8+N9+ N10) = 58*10

One number is given which is 40. Thus,

(N1+N2+N3+N4+ N5+N6+N7+N8+N9+ 40) = 580

(N1+N2+N3+N4+ N5+N6+N7+N8+N9) = 580–40

(N1+N2+N3+N4+ N5+N6+N7+N8+N9) =540

Now there are 9 numbers remaining whose sum is 540. Thus there mean is-

540/9 = 60

So 60 is the answer.

I hope the answer is helped you!
