Assume x and y are the two numbers :
x + y = 80 - - - - (a)
Also, we know that x = y - 18
Replace the values of x in (a)
y - 18 + y = 80
2y = 98
y = 49
x = 49 - 18 = 31

Step-by-step explanation:
Given that :
10 can finish a job in 6 hours ; if job must be done in 5 hours (Given the same rate) ; number of 4P's parent who can finish the job ;
