One nukber is 7 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 604, find the numbers

Question

Has to be in order of first, second, third

Answer 1

If x is the first number, y the second number and z the third number then by the assumptions we have that y=7x and z=x+100 and x+y+z=604. Hence, we have x+7x+x+100=604 which implies that 9x=504 or in other words x=56, y=392 and z=156.
