I think of a number,it is four times as great as another number which is two less than twenty, What is the number?

Answer 1

The other number is 20-2=18. Four times this number is 4*18=<<4*18=72>>72. Therefore, the number is 72.

Answer 2

My clock has gone wrong and chimes three times at one o'clock,four times at two o'clock and so on.it is also half an hour fast, what is the correct time when the clock has just chimed eight?

Answer 3

If the clock chimes three times at one o'clock and four times at two o'clock, then the clock gains one chime every hour. Therefore, when the clock has just chimed eight, the actual time is eight chimes minus eight half-hour increments or four hours.

So the correct time is four o'clock.
