Maths Week: Your Saturday morning puzzle
Part One.
MATHS WEEK KICKED off at the weekend and as is our annual tradition here, we’re setting you a puzzle a day with all answers published on site tomorrow morning.
Get puzzling!
THIS MORNING’S Q:
On the tombola stand at the fair, tickets ending in a 5 will win a bottle of wine, tickets ending in a 0 will win a bottle of brandy and tickets ending in a 1 will win a box of chocolates.
You ask how many tickets are in there altogether and you’re told:
- If you bought 50 tickets you’d be sure of winning a bottle of wine.
- If you bought 60 tickets you’d be sure of winning a bottle of brandy.
- If you bought 40 tickets you’d be sure of winning a box of chocolates.
“But what chance have I of winning something?” you ask.
“You have a 2 in 3 chance of winning something,” the tombalist replies.
How many tickets in the draw?
We’ll have a second puzzle this evening for you on site – happy Saturday!
All answers will be published on TheJournal.ie on Sunday morning.
