A sign in front of a roller coaster says ''you must be 40 inches tall to ride". What percentage of this height is A). 34 inches and B). 54 inches

Solution :

It is given that " You must be 40 inches tall to ride."

The formula used will be :

%  $=\frac{V}{T} \times 100$

Where, V is the value of the percentage to be calculated

            T is the value out of which the percentage of V is to be calculated.

A). What percentage of 40 inches is 34 inches

Where, V is 34 inches and T is 40 inches.

Therefore, the percentage of 34 inches in 40 inches will be

$\frac{34}{40} \times 100$

= 85 %

B). What percentage of 40 inches is 54 inches

Where, V is 54 inches and T is 40 inches.

Therefore, the percentage of 54 inches in 40 inches will be
