Question

the present ages of sunita and smita are in ratio 3:5 . if sunita had been 4 years older and smita 4 years younger , the age of sunita would have been 3 times the age of smita. find their present age

Answer 1

Age of sunita= 3x
Age of smita = 5x

Answer 2

The present age of Sunita is 4 years and Smita's present age is 6.67 years.

• The present ages of sunita and smita are in the ratio 3:5.

• Now let the common multiple be x.

• Now sunita's age is 3x and smita's age will be 5x.

• If sunita had been 4 years older and smita 4 years younger, then the age of sunita would have been 3 times the age of smita.

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

3x+4 = 15x -12

16 = 12x

x = 4/3

• Therefore, sunita's present age is 3x = 4 years .

• Smita's present age will be 5x = 6.67 years.
