Question

The ratio of ages of Aman and Boman is 3 :
4. Five years hence, the ratio changes to 7 :
9. Find their current ages (in years).
1] 15 and 20 2] 60 and 80
3] 3 and
4
4 ] 30 and 40​

Answer 1

Answer:

4 :30 and 40

Step-by-step explanation: let the present ages be 3x and 4x

five year later

age of aman= 3x + 5

age of boman = 4x +5

given ratio = 7:9

3x+5/4x+5 = 7/9

7(4x+5)= 9(3x+5)

28x +35 = 27x+45

28x-27x =45-35

x = 10

current ages:

of aman = 3*10= 30

of boman = 4*10 = 40
