Answer 1

I do not understand your long first sentence.

I will attempt to make sense out of it

let number of 5 centavo coins be x
let the number of 10 centavo coins be y
let the number of 25 centavo coins be z

"25 centavo coin is 3 times as many 5 coinand"
---- z = 3x
"the 25 centavo coins is two more than 10 centavo"
---> z = y+2 or y = z - 2
then y = 3x - 2

5x + 10y + 25z = 490
5x + 10(3x-2) + 25(3x) = 490
110x = 510
x = 4.63...

can't have partial coins, question is faulty
