Question

A number is as much greater than 21 as it is less than 71. What is the number

Answer 1

Let the number be x.
So, 21 Let the difference between x and 21 AND x and 71 be y.
So,
21+y =71-y
2y = 71-21=50
y=50/2=25
So the number x is
x=21+y = 21+25=46
x =71-y =71-25 = 46
So, the number is 46.

Answer 2

The number which is as much greater than 21 as it is less than 71 is the average of 71 and 21.

The number = (71+21)/2 = 92/2 = 46
