Question

I understand this question is really easy but the answer I found isn't one of the options and I have spent 30 minutes on this assignment and if I get this question wrong I have to retake the whole thing pls help the answer I found is 210 but it's not on there pls help

Answer 1

rose 40%
original=100%, now it is 140%

140% of original=now
140% of orignal=350
1.4 of original=350
divide both sides by 1.4
original=250

answer is C
other way

350/140=x/100
35/14=x/100
times both sides by 1400
3500=14x
divie both sides by 14
250=x


C is answer
