My age this year is multiple of 7 Next year it will be a multiple of 5 I am more than 20 years of age but less than 80 How old will I be 6 years from now?
This isn't too tough because the possibilities are few.
The multiples of 7 between 20 and 80 are:
21, 28, 35, 42, 49, 56, 63, 70, and 77.
Of these, when you add 1 ("next year") only one of them becomes a multiple of 5:
49 + 1 = 50
So my age this year is 49. 6 years from now I'll be 55.
