Question 934862

ram is 7 times old as his daughter. after 5 years he will be 5 times old as his daughter. what are their present age?
<pre>
Let daughter's current age, be D
Then Ram's current age = 7D
We then get: 7D + 5 = 5(D + 5)
7D + 5 = 5D + 25
7D - 5D = 25 - 5
2D = 20
D, or daughter's current age = {{{20/2}}}, or {{{highlight_green(10)}}}
Ram's current age: 7(10), or {{{highlight_green(70)}}}
