x+y+z =6000
X+Y+Z=48 ( taking X as 2016- x same has been done for y and z )
Which gives u 50c2 =1225
Now cases where X and Yare same
2X + Z =48 ( 25 cases where Z is an even no till 48)
( similarly we have 2 more cases when X and Z are equal and when Y and Z are equal)
Also the case where all X,Y,Z are same (16 each, but this case has been counted 3 times so we need to balance hence
1225-25*3 +2 = 1152
In this all 3 are unequal and one sixth of the cases will give u when. X< Y<Z will happen
Hence 1152/6= 192
Hence the solutiom
