answer is 25
as 1 dimes=10cents
and 1nickel =5cents
1$=100cents
according to the question
by conversion of nickel and dime to dollar we get
X/20 + Y/10=5.25(X indicates the number of nickels and Y nob of dimes).......(i)
again
Y=X+15
therefore
X+2Y/20=5.25(from i)
=>X+2X+30=105
=>3X=75
=>X=25
number of nickel is 25

cross check
25*.05+ 40*.1
=1.25+4
=5.25
