Question

In the graph you can find the takings of a chocolate bar for $8$ months.

Answer the following question:

Find the percent increase for the month May and June.

• A. $10\%$
• B. $25\%$
• C. $30\%$
• D. $50\%$

Answer 1

The correct option is B $25\%$

From the given frequency polygon,

Number of chocolates taken in Jan $=50000$

Number of chocolates taken in Feb $=40000$

Number of chocolates taken in Mar $=35000$

Number of chocolates taken in Apr $=45000$

Number of chocolates taken in May $=40000$

Number of chocolates taken in June $=50000$

Number of chocolates taken in Jul $=60000$

Number of chocolates taken in Aug $=60000$.

$\therefore$ Percent increase for month May and June $=$ $\frac{50000-40000}{40000}\times 100\%$ $=25\%$.

Hence, option $B$ is correct.
