Tom will be 25 years old in n years' time. If he is 5 years younger than Bade's present age.
A
(30 - n)years
B
(20 - n)years
C
(25 - n)years
D
(30 + n)years
correct option: a
Let Tom's present agr be x.
Then x = 25 - n
If Tom is 5 years younger than Bade, then Bade's present age is x + 5 = 25 - n + 5
= (30 - n)
Then x = 25 - n
If Tom is 5 years younger than Bade, then Bade's present age is x + 5 = 25 - n + 5
= (30 - n)
