Number of ways to choose 3L shape squares from a 2 x 2 square = 6 x 4 = 24
Number of ways to 3L shape squares around the shaded figure = 6
Total number of ways to choose the 3L shape figure = 24 + 6 = 30

Let the number of packages A,B and C be x, y and z respectively

x + y + z = 36 ---------------- ( 1 )
9x + 9y + 6z = 288 ---------- ( 2 )
3x + 6y = 105 ---------------- ( 3 )

9x + 9y + 9z = 324 ………. ( 1 ) x 9 = ( 4 )

( 4 ) – ( 2 )
3z = 324 – 288 = 36
z = 12

x + y = 24
6x + 6y = 144 ----------------- ( 5 )

( 5 ) – ( 3 )

3x = 144 – 105 = 39
x = 13

No. of packages of type A = 13
