Answer:
68
Step-by-step explanation:
Let the common factor be x
Now 1st no. = 15x
2nd no. = 19x
Adding 2 to each of the no.
By the problem,
15x+2/19x+2=4/5
=>75x + 10= 76x +8
=> 10-8= 76x-75x
=> x=2
Now,
1st.no= 15×2=30
2nd no.= 19×2= 38
Adding the no. = 30+38= 68

(15x+2)/(19x+2)=4/5
Or, 75x+10=76x+8
x=2
Number are 30 and 38
