Quant problems for Revised GRE pattern
These are some problems from the Maths review doc provided by ETS. Can somebody provide the solutions??
Q 1. When the positive integer n is divided by 3, the remainder is 2 and when n is divided by 5, the remainder is 1. What is the least possible value of n?
Q 2. Two cars started from the same point and traveled on a straight course in opposite directions for exactly 2 hours, at which time they were 208 miles apart. If one car traveled, on average, 8 miles per hour faster than the other car, what was the average speed of each car for the 2-hour trip?
Q 3. A group can charter a particular aircraft at a fixed total cost. If 36 people charter the aircraft rather than 40 people, then the cost per person is greater by $12.
(a) What is the fixed total cost to charter the aircraft?
(b) What is the cost per person if 40 people charter the aircraft?

Saandeep SreerambatlaWhen you write the first question in equations format, you get:
3x+2 = N
5y + 1 = N
Solving these equations you get: 5y-3x = 1.
The least possible is y = 2 and x = 3 so n = 11. -
gretakerExactly. You have to check for the least possible values.
