| 290833 | 2004-11-12 06:02:00 | Sorry - I find the "don't understand the question" excuse a bit weak. Look at the question in the post and tell me which part you don't understand. Maybe i'm to old for you txters but it seems perfectly clear to me | Dally (6292) | ||

Sports64 = Sports04 - 10 = 600 - 1 = 590 Comp64 = 590 x 5 = 2950 Proof1 : Comp04 = ( (Comp64 / 5) +10 ) x 17.5 10500 = ( (2950 / 5) +10 ) x 17.5 10500 = 10500 and Proof2 : Comp04 = (Comp64 x 3.5) + (10 x 17.5) 10500 = (2950 x 3.5) + 175 10500 = 10325 + 175 10500 = 10500 q.e.d. |

| 290835 | 2004-11-12 06:38:00 | Sorry Andrew93 but you have the wrong answer | Dally (6292) | ||
| 290836 | 2004-11-12 07:03:00 | 700. As for the equation - it's too long ago..... :D :D | Miami Steve (2128) | ||
| 290837 | 2004-11-12 07:09:00 | Miami Steve Your answer is wrong too but we are getting closer | Dally (6292) | ||
| 290838 | 2004-11-12 07:26:00 | Is this a trick question depending on the interpretation of "10 more sports"? | andrew93 (249) | ||
| 290839 | 2004-11-12 07:27:00 | or the "3.5 times greater". If it''s one of those stoopid questions that what a complete WOFTAM. My 2c |

| 290840 | 2004-11-12 07:34:00 | wats the answer then and how do you know it | ApeNz (4220) | ||
| 290841 | 2004-11-12 07:34:00 | Bugger the formula. The number of sports played at the 1964 Olympics was 19 - and that's a fact (www.cbc.ca). :D |
