Question

John is 7 years older than half of his sisters age. If John is 35 years old, how old is his sister ?

Answer 1

Answer:

First, look at when John is 6. It says that his sister is half his age. That means 6/2 = 3. John’s sister is 3, and take note, three years below John’s

Nowadays, John is 70. How old is the sister? Well, if his sister was 3 years younger than him 64 years ago, wouldn’t it be the same now? If two numbers grow/shrink the same amount at the same time, that are always the same distance apart.

So, overall, John’s sister was 3 when he was 6, here years difference. John is now 70, so that means… that his sister is 67!
