Question 1153967
The sum of the current ages of larry and his father is 75. In 25 years, Larry's father will be thrice as old as Larry today. If larry will be 50 then, how old will his father be?
<pre>If Larry will be 50 in 25 years, then Larry is currently 25
With the sum of their ages being 75, then {{{highlight_green(matrix(1,7, father, must, "be:", 75 - 25, "=", 50, years-old))}}}
You should now be able to find his father’s age, 25 years from now.
<b><u>OR</b></u>
Let father's age, in 25 years be F
Then father’s current age is: F - 25
If Larry will be 50 in 25 years’ time, then Larry is now 50 - 25, or 25
With their current ages summing to 75, we get: F - 25 + 25 = 75
F, or {{{highlight_green(matrix(1,4, father, "is:", 75, years-old))}}}
