Question

7800 People visited an art exhibition. There were 3 times as many adults as children. How may adults were there.

Answer 1

Step-by-step explanation:

Let the the number of children be x.

So number of adults will be 3x.

According to the Question,

x+3x=7800

4x=7800

x= 1,950

Number of adults= 3x = 3 × 1,950= 5,850.

So number of adults = 5,850

Answer 2

Answer:

The total number of adults was 5850

Step-by-step explanation:

Given,

We have total number of people who visited the art exhibition to be 7800. There are adults as well as children in the art exhibition. We need to find out the total number of adults attending the art exhibition.

Let us consider the number of children to be x and the number of adults to be y then,

x + y = 7800

We have also been given additional information that the number of adults were exactly 3 times that of the children then,

y = 3x

Applying this in the above equation,

x + 3x = 7800

4x = 7800

x = 1950

y = 3x = 1950 * 3 = 5850
