Total number of ways = 4x5 = 20.

Favourable cases (2,7) (3,6) (4,5) and (5,4)

So 4/20 = 0.2

You guys dont seem to like the verbal section of this forum :P

You've got some great questions for the quant section. Do you guys have any similar yorkers or googly for the verbal section. :)

Infact both me and Sureshbala are no longer a GMAT aspirant, that is history for us. We are currently Quant Instructors in our separate fields of business. You may call it our duty, passion about our subject, or whatever for why we use to write for these sites for nothing. But mals24, I don't want to dissappoint you so we would definitely try and write and of course discuss problems and contents, which could probably be helpful for the aspirants of your kind, at large. B-)

Yes, we will definitely try to do this once we are free. Right now a bit busy with the official work back here in office. Once it is done...you will find us more active
