Question

$\text{35 inches of a cardboard sheet is lost}$ $\text{as scrap.}$
$\text{What is the useful length in inches if}$ $\text{the sheet is 6 meters long?}$

• A. $\text{162 inches}$
• B. $\text{187 inches}$
• C. $\text{175 inches}$
• D. $\text{199 inches}$

Answer 1

The correct option is D $\text{199 inches}$

$\text{Total length of the sheet}$ $\text{= 6 meters}$

$\text{1 meter = 39 inches (approximately)}$

$\text{Let's calculate the total length}$ $\text{of the cloth first.}$

$⟹\text{1 meter = 39 inches}$

$⟹\text{6 meters = 39}\times 6\text{inches}$
$\text{= 234 inches}$

$\text{Out of 234 inches, 35 inches of}$ $\text{of the sheet is removed as scrap.}$

$\text{Hence, the useful length}$ $\text{of the cloth is:}$

$⟹\text{234 inches - 35 inches}$
$\text{= 199 inches}$

$\text{Thus, useful length of the cardboard}$ $\text{sheet left is 199 inches.}$
