Read the given information and answer the question that follows.

Daily Icecream Sales by Flavour If 400 chocolate ice creams are sold in a day, how many vanilla ice creams are sold?

The correct option is 350.

From the pie chart titled "Daily Icecream Sales by Flavour":

- Percentage share of Chocolate ice cream = 40%
- Percentage share of Vanilla ice cream = 35%

We are given that 400 chocolate ice creams are sold in a day.

Let the total number of ice creams sold in a day be $T$.

According to the given data:

$40\%\text{ of }T=400$

$\frac{40}{100}\times T=400$

$T=\frac{400\times 100}{40}=1000$

So, the total number of ice creams sold in a day is 1000.

Now, we calculate the number of vanilla ice creams sold:

$\text{Vanilla Ice Creams}=35\%\text{ of }T$

$\text{Vanilla Ice Creams}=\frac{35}{100}\times 1000=350$

Therefore, 350 vanilla ice creams are sold in a day.
