Question

if the weight of the 12 sheets of paper is 40 gram how many sheets of the same paper would weight 5/2 kilogram

Answer 1

Answer:

12sheets = 40 grams

1 sheet = 40/12 grams = 10/3 grams

1 kg = 1000 grams

5/2 = 5/2×1000 = 250 grams

no. of sheets = 250/10/3 = 250×3/10

= 75

so, no. of sheets = 75 sheets.
