<U>Solution</U>


<pre>
Take off 5 dimes from the collection, for a moment.

You will have equal number of quarters and dimes in the remaining collection, totaling 295 - 50 = 245 cents.

Group them in pairs, one quarter and one dime in each pair.

Each pair is worth 25 + 10 = 35 cents.

The number of such pairs is {{{245/35}}} = 7.

It implies the answer.
