Question

solve the following equation
The ages of hari and Harry are in the ration 5:7.Four years from now the ratio of their ages will be 3:4 .Find their present age.​

Answer 1

Answer:

On solving the two equations we get x and y. Multiply (1) by 4 and multiply (2) by 3, we get, 20x + 16 = 12y 20x + 16 = 12y And 21x + 12 = 12y 21x + 12 = 12y respectively. Now, the present ages of Hari and Harry are 5x and 7x,
