1 large is equivalent to 2 small
so
2 large is equivalent to 4 small

&
Lina has effectively bought
2 large & 5 small
which are
4 small & 5 small
which are
9 small

9 small = 945 g
1 small = 105 g

next,
give to bro
1 large & 1 small
which are
2 large & 1 small
which are
3 small

so bro got
3 small = 315 g



ALT

before
small: 5u
large: 2 x 2u = 4u

after
small: 4u
large: 2u

bro received = 3u

5u + 4u = 945
u = 105
3u = 315

Nope, 1 large equals to 2 small. Hence instead of 1 box you could draw 2 boxes for per pack of large bag under the model. This would help you easily calculate the answer more accurately. Give it a try :)
