Sam is 5 years old. His older brother, Tom, is three times as old as Sam. When Sam is 20, how old will Tom be?

Tom is three times as old as Sam. So when Sam is 20, Tom will be three times as old as that. Multiply 20 by 3 and you will get 60. So when Sam is 20, Tom will be 60.

Constantine's logic is flawed.

The difference in ages between the two siblings stays the same, but the ratio of their ages changes

Just because at some point you are 3 times as old as your brother,
e.g. 15 vs 5
in five years that ratio is no longer 3:1 but rather 2:1
15 + 5 = 20
5 + 5 = 10

ratio = 20/20 = 2 and not 3

30

Wrong . . .the bro is 5 + 20 =25 in 20 yrs tym . . Hs bro is 3 times is age =3 x 25 =75. . Which means when he is 25 ys hs bro wil be 75 yrs

Sorry there is mistake d quest didn't say in 20 yrs tym xo . D ansa is dat if sam is 20 yr tom wil be 20 x 3 =60yr

To find out how old Tom will be when Sam is 20, we need to determine the age difference between them.

First, we establish the current age of Sam. The given information states that Sam is currently 5 years old.
Next, we find Tom's current age by stating that Tom is three times as old as Sam. Therefore, Tom's current age is 3 * 5 = 15 years old.

To determine how many years later Sam will be 20 years old, we subtract Sam's current age from his target age of 20, which gives us 20 - 5 = 15 years.

To obtain Tom's age when Sam is 20, we add the number of years (15) to Tom's current age. Thus, Tom will be 15 + 15 = 30 years old when Sam is 20.
