Answer:
Let the two numbers be x and y
as per problem sum of two numbers is 100
x+y=100.........................eq1
their difference is 50
x−y=50.................................eq2
on adding both equations we get
x+y=100
x−y=50
_______________________
2x=150
x=75
putting value of x=75 we get y=25
75+y=100
y=25
ratio of two numbers will be 75:25=3:1
