Answer 1

Answer:

The required number is 51.

Step-by-step explanation:

Let the required number be x.

Given that average of 4 numbers is 60.

So, average = total sum/4

60 = total sum/4

So, total sum of 4 numbers = 240

Now, given that one of them is less than the average of remaining numbers by 12.

So, x = (240 - x)/3 - 12

4x = 204

x = 51
