There are 4 dimes out of 10 coins total.
The probability of picking a dime is 4/10 = 2/5

That coin is put back, meaning the original state of the jar has not changed. In turn, it leads to the probability of picking a quarter to be the same as if it was selected first.
If on the other hand the coin wasn't put back, then the probability for the second selection would change.

There is 1 quarter out of 10 coins.
The probability of picking a quarter is 1/10

Multiply the two fractions mentioned:
(2/5)*(1/10) = 2/50 = 4/100 = 0.04

Answer: 0.04
