Nickel = 5 cent

Dime =10 cent

Quarter =25 cent

no of nickels =x

no of dimes =x+2

no of quarters =x+2+4=x+6

Total value = 5x+10(x+2)+25(x+6)= 5x+10x+20+25x+150 = 40x+170 =530

40x =530-170=360

x=9

No of nickels =9

No of dimes =11

No of quarters= 15

Verification 9+0.05+11*0.1+15*0.25 dollars = 0.45+1.1+3.75=5.30
