Question #78696

Answer 1

`45`

Explanation:

25% dimes, so other coins 75%, that is `180*75% = 135`.

Now after adding more dimes, other coins are 60%, so 135 coins is 60% of the total coins. So, total number of coins `= 135*100/60 = 45*5 = 225`

Earlier total coins were 180, now there are 225 coins, so `225-180 = 45` dimes were added.
