If I had one more sister I would have twice as many sisters as brothers. If I had one more brother I would have the same number of each.
How many brothers and sisters have I?

Answer

Three sisters and two brothers.
This can be solved by simple deduction, but if algebra is used let x be the number of sisters and
y the number of brothers:
x+ 1= 2y
y+ 1= x

so y =2
or x + 1= 2x - 2
so x = 3

There are 10 lit candles on a table. A strong breeze comes and extinguishes 2 of the candles. When you come back later, you see that 1 more has been blown out.To make sure no more flames go out, you shut the window. Assuming the wind doesn't extinguish any more candles and you don't relight the extinguished candles,
how many candles do you have left in the end?

Answer

There are 3 candles left in the end. The 7 candles that manage to stay lit will melt down completely. The only candles that remain in the end are the 3 that are extinguished by the wind and therefore stay intact.
