Answer:

The largest card is 5x  that is 5 x 2.25=11.25[/tex]

Step-by-step explanation:

Let the fourth card be x

We have been given the third card is 5 times the fourth card means third card is 5x

Ans second card is one third of the third card means second card is \frac{5x}{3}

And the first card is twice the second card means \frac{10x}{3}

So, we have given the average of all four cards

average=\frac{\frac{10x}{3}+\frac{5x}{3}+5x+x}{4}=24.75

\frac{33x}{3}=24.75

11x=24.75

\Rightarrow x=2.25

The largest card is 5x  that is 5\cdot 2.25=11.25
