Hello, AZHAR!
I must assume that you've been taught about Combinations
. . before you were assigned this problem.
Saqib buys 3 cows, 2 pigs and 4 hens from a man who has 6 cows, 5 pigs and 8 hens.
How many choices does the Saqib have?
He buys 3 of the 6 cows: .$\displaystyle _6C_3 \:=\:20$ choices.
He buys 2 of the 5 pigs: .$\displaystyle _5C_2 \:=\:10$ choices.
He buys 4 of the 8 hens: .$\displaystyle _8C_4 \:=\:70$ choices.
Therefore, he has: .$\displaystyle 20 \times 10 \times 70 \:=\:14,\!000$ choices.
