**How many times do they eat a week?**
A candle
burns after 15 minutes.

**How long it takes to burn 10 candles if they were lit at the same time?**

People eat 3*7=21 times in a week.

ReplyDeleteAll candles will burn out after 15 minutes as they were lit together ;-)

The 2 line with -2 +2 ...... =4 (the first two digits)

Very clever indeed. Thanx a lot.

We didn't get the 2011 question. Can you explain?

Dear Demi,

ReplyDeleteYou are really good at maths:-)

You should say -what is the sum of these numbers?

2011. The answer is 4:-)

Thanks for solving our tasks. We will publish more next week:-)

2+0+1+1=4
