Answer 1

Answer:

Let 3 helmet = 36

.•. 36/3=12 (.•. hence helmet=12)

now let bag =x

2 bag + 1helmet = 20

.•. 2x +12=20

2x =20-12

x = 8/2 = 4 (.•. hence bag =4)

now flare gun = y

1bag + 2gun=10

4 + 2y =10

2y =10-4

y =6/2 = 3 (.•. hence gun=3)

ACCORDING TO QUESTION

1HELMET - 1BAG × 1FLARE GUN

12 - 4 × 3

12 - 12

Thanks for asking questions!!.

Answer 2

Answer:

one helmet =12

then three helmet=36

and one bag=4

then two bag =8

and two bag and one helmet=4+4+12= 20

now one bag =4

and one gun =3

then two gun=6

and one bag and two gun =6+4=10

helmet- bag× gun

12-4×3

12-12=0
