Answer 1

Answer:

change your numbers accordingly

Average of 3 original numbers is 87

Step-by-step explanation:

Let consider 3 original no as a, b, c

Given that average of any 2 nos + third no is 168,174,180

1) (a+b) /2+c=168 solving we get

(a+b+2c) /2=168..(1)

Similarly

2) (b+c) /2+a=174

(2a+b+c) /2=174..(2)

3) (a+c) /2+b=180

(a+2b+c) /2=180..(3)

Adding eqn (1) +(2) +(3)

(4a+4b+4c) /2=522

Solving we get

(a+b+c) =261

Average of three nos is

(a+b+c) /3=261/3=87
