A collection of nickels, dimes, and quarters is worth $5.30. There are two more dimes than nickels and four more quarters than dimes. How many quarters are in this collection of coins?
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
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
