Question

6. If the weight of 12 sheets of thick paper 40 grams, how many sheets of the same
paper would weigh 21/2 kilogram?​

Answer 1

Answer:

answer is 3150

Step-by-step explanation:

40grams= 12 sheets of paper

21/2*1000=10500grams =?

cross multiply 10500*12/40 = 3150

Answer 2

ANSWER:

WEIGHT OF PAPERS(g)   40        2500(5/2×1000)

NO.OF PAPERS                 12                 x

As the weight of the papers increases the no. of papers also increases

It is a Inverse variation

x y = k (constant of variation)

40/12=2500/x

12×2500÷40 = x

x=750

Ans:750 sheets of thick paper weigh 2500 gram or 5/2 kilogram
