Answer 2

Answer:

3. There were 5 footballs sold for every 2 basketballs.

Step-by-step explanation:

Let the number of basketball = x and the number of football = y.

It is given that, 'the number of footballs were 2.5 times the number of basketballs last year'.

That is, $y= 2.5x$

That is, $\frac{y}{x}=\frac{2.5}{1}$

That is, $\frac{y}{x}=\frac{5}{2}$

That is, the ratio of football to basket ball is 5 : 2.

Which means, 'For every 2 basketballs, 5 footballs were sold'.

So, option 3 is true but options 1 and 4 are not true.

Moreover, 'if there were total 35 balls sold', we have,

$x+y=35$

i.e. $x+2.5x=35$

i.e. $3.5x=35$

i.e. x= 10

So, $y= 2.5x$ implies $y= 2.5\times 10$ i.e. y= 25.

Thus, for total 35 balls sold, 10 were basketballs and 25 were footballs.

So, option 2 is not true.

Hence, the correct answer is option D.
