Question

The ratio of ages of two sisters Sherya and kavita is 3:4. After 5 years It will be 5:6, what are their current ages.​

Answer 1

Answer:

Let the present age of Shreya =3a and age of Kavita =4a . After 5 years, age of Shreya =3a+5 = 3 a + 5 and age of Kavita =4a+5 = 4 a + 5 . Hence, present age of Shreya =3a=15 = 3 a = 15 years and age of Kavita =4a=20 = 4 a = 20 years.

Answer 2

Answer:

Let the present age of Shreya =3a  and age of Kavita  =4a.

After 5 years, age of Shreya =3a+5  and age of Kavita  =4a+5.

Given, 3a+5:4a+5=4:5

=>4a+53a+5=54

On cross multiplying,

15a+25=16a+20

a=5

Hence, present age of Shreya =3a=15 years and age of Kavita  =4a=20 years.
