When Linda's mother gave her 2 more dimes, the total number of dimes increased to 2+2 = <<2+2=4>>4 dimes.
She also increased the total number of quarters to 6+10 = <<6+10=16>>16 after her mother gave her 10 more.
The total number of dimes and quarters she has is 16+4 = <<16+4=20>>20
Linda's mother also gave her twice as many nickels as she has, a total of 2*5 = <<2*5=10>>10 nickels.
The total number of nickels she has increased to 10+5 = <<10+5=15>>15
Altogether, Linda has 20+15= <<20+15=35>>35 coins.
