Ages of abdul and vikas are in the ratio of 5:7 four years from now the ratio of theit ages will be 3:4 find their present ages

Answer 1

Answer:

age of abdul=20

age of vikas=28

Step-by-step explanation:

let the ages be 5x and 7x

so,

[5x+4]/7x+4=3/4

4*[5x+4]=3*[7x+4]

20x+16=21x +12

hence,

x=4

so,

age of abdul=5x=20

age of vikas=7x=28

Answer 2

Answer:

20 and 28

Step-by-step explanation:

let the age be x

5x/7x

after four years

5x+4/7x+4 = 3/4

by doing cross multiplication

4(5x+4) = 3(7x+4)

x = 4

5x = 20 and 7x = 28
