Question

x,y and z are positive integers such that x 13 years ago

Answer 1

Try to break this question down. To find the maximum value of x+y+z. We know that z is dependent on x. The bigger x is, the bigger z is. We also know that y is bigger than x.

From this we can deduce that finding max value of x will solve our problem!

x+y = 201. x<y
max value for x is 100, meaning that y is 101. and z is 300

Answer 2

Therefore x+y+z =501
