Question

if 15 chart papers together weigh 50grams how many of the same type will be there in a pack of 2.5grams​

Answer 1

Given that 15 chart papers weigh 50 grams

So,

One chart paper will weigh = 50/15

Now,

We need to find how many such chart papers would weigh 2.5 grams, We know one chart paper weigh 50/15 so,

Number of chart papers = 2.5 / (50/15)

☛ 25 × 15 / 25 × 20

☛ 15/20

☛ 3/4

Hence, there is three fourth of such a chart paper weighing 2.5 grams.
