Question

if the thickness of 500 sheets of paper is 3.5cm then what would be the thickness of 275 sheets of the same paper.

Answer 1

Thickness of 500 sheets of paper = 3.5 cm
Thickness of 1sheet of paper = 3.5/500 =0.007
Therefore Thickness of 275 sheets = 0.007× 275 =1.925

Answer 2

The thickness of 275 sheets of the same paper is 1.925 cm.

• The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.
• In the unitary method, the value of a unit quantity is determined before the values of other units are determined. Direct variation and inverse variation are the two different sorts of variations it has.
• When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. For instance, a rise in the quantity of commodities will result in higher costs.

Here, according to the given information, we are given that,

The thickness of 500 sheets of paper is 3.5 cm.

Then, the thickness of 1 sheet of paper is $\frac{3.5}{500}$ cm.

Then, the thickness of 275 sheets of the same paper is $\frac{3.5}{500}.275 = 1.925$ cm.

Hence, the thickness of 275 sheets of the same paper is 1.925 cm.
