At a movie night,1/4 of the persons were boys,5/8 were girls and the rest were adults. If there were 56 more girls than adults how many persons were in total?

Given:

Number of boys = of the total persons.

Number of girls = of the total persons.

Remaining persons are adults.

There were 56 more girls than adults.

To find:

The number of total persons.

Solution:

Let x be the number of total persons. Then,

Number of boys =

Number of girls =

Number of adults = Total persons - Boys - Girls

                             =

                             =

                             =

There were 56 more girls than adults.

Girls = Adults + 56

Multiply both sides by 2.

Therefore, the total number of persons is 112.
