[求助]二道簡單 答案卻很多的題目

bpan007

个人存钱原来就有800元了，第一星期存1元，第而个星期存2元，以后每个星期比前一个星期多一元，问50个月后工有多少钱
【确定】2075 (3次) 考试时，这道题数字变了

我有看到別人寫179900
但是我怎麼算卻跟這些答案不一樣
而且我認為得出來的錢應該比二千元多
求教各位大俠是如何計算這個題目的

m 是75，98，140 的公倍数，问那个正确
a， 忘了，但不对 b m为49的倍数 c m大于14000
【确定】b （5次）
【版本二】If K is common multiple of75, 98 ,140, which of the following must be true?
Ⅰ. K is a multiple of 9
Ⅱ. K is a multiple of 49
Ⅲ. K is greater than 14000

我一直都覺得是 III , II
對嗎?
