Question

How many number of ducks are there in less than $60$ ponds?

• A. $59$
• B. $39$
• C. $29$
• D. $19$

Answer 1

The correct option is A $59$

From the histogram, the class width gives the number of ducks:

$0-19=30$ number of ponds.

$20-39=20$ number of ponds.

$40-59=25$ number of ponds.

$60-79=10$ number of ponds.

$80-99=20$ number of ponds.

$100-119=15$ number of ponds.

Therefore, $30+20+25=59$ number of ducks are there in less than $60$ ponds.

Hence, option $A$ is correct.
