    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: . _6C_3 \:=\:20 choices.

    He buys 2 of the 5 pigs: . _5C_2 \:=\:10 choices.

    He buys 4 of the 8 hens: . _8C_4 \:=\:70 choices.


    Therefore, he has: . 20 \times 10 \times 70 \:=\:14,\!000 choices.
