Question

The bar graph shows information about the sales of wrist watches from five branches

A_{1}, A_{2}, A_{3}, A_{4}

and

A_{5}

of company 'ABC' in 2016 and 2017. If the sum of sales of all branches in 2016 is

350

units and in 2017 is

450

units, find the ratio of total sales of all branches for the year

2016 to 2017.

Accepted Answer

Given:
Total sales of all branches for the year 2016 =

350

Total sales of all branches for the year 2017 =

450

We need to calculate the ratio of total sales of 2016 to 2017:

Ratio = \frac{Total Sales in 2016}{Total Sales in 2017} = \frac{350}{450}

Simplify the fraction by dividing both numerator and denominator by

50

:

Ratio = \frac{350 \div 50}{450 \div 50} = \frac{7}{9}

Thus, the ratio is

7 : 9

.
