Question

Present ages of Kiran and Isha are in ratio of 3:4. Five years from now the ratio of their age will be 4:5
Find their present ages
​

Answer 1

Answer:

Present ages of Kiran and Isha respectively are = 15 and 20

Step-by-step explanation:

Present ages of Kiran and Isha = x and y

according to given ratio:

x : y = 3 : 4

4x = 3y

x = 3y / 4

Five years from now:

x+5 : y+5 = 4 : 5

5x + 25 = 4y + 20

5x - 4y = - 5

5( 3y /4) - 4y = -5

(15y /4) - 4y = - 5

15y - 16y = -20

-y = -20

y =20

x = 3(20) / 4

x = 15

Answer 2

the age of kiran = 15years and the age of Isha =20 years
