(a)450
(b)550
(c)650
(d)750

Answer 1

If the weight of 12 sheets of thick paper is 40 grams how many sheets of the same paper would weight 2.5 kilograms?

12 sheets = 40g

1 sheet = 40/12 g

            = 40/12000 kg
            = 4/1200 kg
            = 1/300 kg

{ Let the number of sheets be 'x' }

2.5 = x/300 kg

750 = x

Therefore, the answer is (d) 750
