How about a 'countdown' (like the actual gmat) instead of a 'stopwatch' , however, this one being user-adjustable based on the skill level of the user. So for example, a begineer can set the countdown for 3 mintues, an intermediate skill level user can set it for 2 and an advanced user can set it f...

yep the answer is D. the 5 numbers can be arranged as follows 2, 7, 11,16 and x. Stmt 1 says x is between 7 and 11. so the arrangement becomes 2, 7, x, 11, 16. If u look at this seq carefully , u will notice 2 and 7, 11 and 16 are evenly spaced (diff = 5). So we can ignore them in calculating the va...

From the question we can understand that the ratio of concentrate to water is 1:3. ie 25% of concenrtate is mixed with 75% of water to create 100% juice. Now the problem asks for how many 12 ounce cans are needed to make 200 6 ounce cans. 200 6oz cans is same as 100 12oz cans. So the problem reduces...

Simple!!.
7% of x = 87.50
ie (7/100)*x = 87.50.
Solve this to get 1250.
Now the import tax is not levied for the first $1000, we need to add 1000 to the above result.
So answer is 2250.

Sanju,
That is called "unintended typo" or "printer's devil". But the typo probably reflected my true inner nature ;-)
