Let the sons age be x years then
- the fathers age is 2x + 5 years, So:-
2x + 5 - x = 25
x = 25 - 5 = 20
The father is 2 (20) + 5 = 45 years answer
You 2l x 2w and blah blah blah blah blah blah blah blah
Idk how many start cards there are o this problem cant be solved...
the answer would be 8.
2 times 8 = 16 minus 5 = 11
There are 120 different possible groups.
(10 * 9 * 8)/(3 * 2 * 1) + 120
