Question

The ratio of present ages of rohan and mohan is 5: 12 Five years hence ratio of their ages will be 3:8 find their present ages ?​

Answer 1

Answer

I am not sure

Let x be the present age of rohan and mohan then present age of mohan is 5x and that of mohan is 7x.

According to 1st condition -

Mohan's age will be 5x+9

mohan's age will be 7x−9

⇒5x+9:7x−9=2:1

⇒

7x−9

5x+9

=

1

2

⇒(5x+9)=2(7x−9)

⇒5x+9=14x−18

⇒5x−14x=−18−9

⇒−9x=−27

⇒x=3

Present age of mohan is 5x=5×3=15

Present age of rohan is 7x=7×3=21

hence, solved.

Answer 2

Answer:

This is not possible.

Step-by-step explanation:

Let Rohan=x, Mohan=y

now, x/y=5/12 => 12x-5y=0

again (x+5)/(y+5)=3/8 => 8x-3y+25

solving these, x=-125/4 and y=-75.

age can't be negative. Your informations are wrong.
