Hi Zeeshan 01,
As bob bundy points out, if the problem is taken word for word, then my answer is correct. On balance, I think bob bundy's answer is more likely if the phrasing is open to ambiguity. However, the problem appears to have been written in your own words -- could you post the problem as it appears on your problem sheet, unchanged?

Thanks bob.
i like math because it is a "language" which is internationally available.
