Soumya100: don't worry bro
jinyriju: let 7x be the age of john
jinyriju: let 7x be the age of john : let 5x be the age of manoj then , after 10 years,the ages will be 7x+10 and 5x+10 which is equal to 9/7 or 9:7 respectively so the equation will be :- 7x+10/5x+10=9/7(which is nothing but 7x+10:5x+10 =9:7) now after cross multiplying LHS with RHS we get:- 7(7x+10)=9(5x+10) =49x+70=45x+90 subtracting we get:- =49x-45x=90-70 =4x=20 =x=20/4 =x=5 now replacing x with 5 .......we get manoj's age as :5x=5*5= 25years and john's age as 7x=7*5=35 years
