Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 22500.
Given that, weight of (box + gift srticle) = 25 kg
Ratio of weight of box to the weight of gift articles = 1 : 9
Let the weight of the box and that of the gift article be x and 9x respectively.
According to the given question,
⇒ x + 9x = 25
⇒ 10x = 25
⇒ x = 2.5 kg
Weight of articles (in kg) = 9 × 2.5 = 22.5
Weight of articles (in grams) = 22.5 × 1000 = 22500
Hence the weight of the articles (in grams) is 22500.
