Dear Satyam,
to solve this question, you have to consider some cases.
case I : let d=0
a+b+c=24.
You have to distribute 24 identical objects into 3 groups.no of solutions to this = (24+3-1)C(3-1)=26C2
case II : let d=1
a+b+c = 20
You have to distribute 20 identical objects into 3 groups.no of solutions to this = (20+3-1)C(3-1)=22C2
case III : let d=2
a+b+c=16
You have to distribute 16 identical objects into 3 groups.no of solutions to this = (16+3-1)C(3-1)=18C2
case IV : let d=3
a+b+c=12
You have to distribute 12 identical objects into 3 groups.no of solutions to this = (12+3-1)C(3-1)=14C2
case V : let d=4
a+b+c=8
You have to distribute 8 identical objects into 3 groups.no of solutions to this = (8+3-1)C(3-1)=10C2
case VI : let d=5
a+b+c=4
You have to distribute 4 identical objects into 3 groups.no of solutions to this = (4+3-1)C(3-1)=6C2
case VII : let d=6
a+b+c=0
You have to distribute 0 identical objects into 3 groups.no of solutions to this = 2C2
Hence total number of solutions = 1 +6C2 + 10C2 + 14C2 + 18C2 + 22C2 + 26C2
= 861
