Answer 1

Answer:

Answer 4 kg 300gm

Step-by-step explanation:

1kg=1000gm

3kg=3000gm

then, weight=3000+225=3225gm

NOW,

3/4 = 3225

1 = 3225×4/3 [by cross multiplication]

=>12900/3

=> 4300 gm

Hence, the weight of full box of apple is 4300 gm or 4kg 300gm

☆2nd question)

let the other no. be x

then,

1/7×X=2

=>X = 2×7 [By cross multiplication]

=>X = 14

HENCE, the other no. is 14
