Answer 1

Answer:

Step-by-step explanation:

Let the age of renu be r and menu be m

And renu age is 12 years

The ratio of their age is 2:5

》r/m = 2/5

》12/m = 2/5

》 m = 12 ×5 /2

》 m =30

And the ratio of menu age and sum of their age is =m/m+n

=30 /30+12

=30/42

= 5/7

=5:7

Answer 2

Answer:

5:7

Step-by-step explanation:

let the age of Renu be X and Meenu be y

X=12

ratio=2:5

• X/y= 2/5
• 12/y = 2/5
• y = 12×5/2
• y= 30

And the ratio of y and sum of their age is

= y/y+X

=5:7
