Question

present age of Rohit and Mohan are in the ratio 5 ratio 6 then year 10 years from now the ratio of their age will be 6 ratio 7 find their present ages

Answer 1

Heya !!!


Let present age of Rohit and Mohan be 5X and 6X.



After 10 years age of Rohit = ( 5X + 10 )



After 10 years age of Mohan = ( 6X + 10 )



According to question,



Age of Rohit after 10 years : Age of Mohan after 10 years = 6 : 7


5X + 10 : 6X + 10 = 6 : 7



7 ( 5X + 10 ) = 6 ( 6X + 10 )


35X + 70 = 36X + 60



36X - 35X = 70 - 60


X = 10 years



Present age of Rohit = 5X = 5 × 10 = 50 years

And,


Present of of Mohan = 6X = 6 × 10 = 60 years

Here is your answer


suppose present age of rohit and mohan is 5a and 6a.

according to the question
5a + 10÷ 6a + 10 = 6÷7
35a + 70 = 36a + 60
a = 10 yrs
present age of rohan = 5a = 5×10 = 50 yrs
and,
present of age of mohan = 6a = 60 yrs
