Question

if the mean of 12,13,x,17,18,20 is 60 find x​

Answer 1

We know that mean is  the arithmetic average of a set of given numbers. The median is the middle score in a set of given numbers. The mode is the most frequently occurring score in a set of given numbers.

12 + 13 + x + 17 + 18 + 20/6 = 60

25 + 35 + x + 20 = 360

80 + x = 360

x = 360 - 80 = 280 (Answer)
