Puzzles to puzzle you
1. Find the birthday
When asked about his birthday, a man said:
"The day before yesterday I was only 25 and next year I will turn 28."
This is true only one day in a year - when was he born?
2. Ordered times
Mari saw that his oven digital clock was showing 01:23, and noticed that each number was one higher than the number to its left.
He wondered: of all the different clock times from 00:00 to 23:59 in a 24-hour clock, how many are like that? And what exactly are those clock times?
Can you help him out?
3. Mathematical grandmother
Mimi asked her Granny how old she was. Rather than giving a straight answer, she replied:
"I have 6 children, and there are 4 years between each one and the next. I had my first child (your Uncle Pethu) when I was 19. Now the youngest one (your Auntie Janaki) is 19 herself. That's all I'm telling you!"
How old is Mimi's Granny?
