Question

The sum of age of the father and son is 100years now. 5 years ago 2:1 ratio after 10 years what will be the ratio

Answer 1

Answer:

5/3

Step-by-step explanation:

Let the father's age be 'x'

the son's age be 'y'

Now,

x + y = 100                           ( 1 )

x - 5/y - 5 = 2/1

x - 5 = 2y - 10

x = 2y - 5

put x = 2y - 5 in Equation ( 1 )

2y - 5 + y = 100

3y = 105

y = 35

x + y =100

x = 100- 35

x = 65

ages after 10 years =

45 and 75

Ratio = 75/45

         = 5/3
