What is the greatest of 3 consecutive integers whose sum is 24 ?
Pick one: A) 6 B) 7 C) 8 D) 9 E) 5

Solution: The sum of three consecutive integers can be written as n + (n + 1) + (n + 2) = 3n + 3   If the sum is 24, we need to solve the equation 3n + 3 + (  + 1) + (  + 2)= 
+ (  + 1) + (  + 2) = 3
3n + 3   If the sum is 24, we need to solve the equation 3n + 3= 24;   => 3n = 21;   => n = 7   The greatest of the three numbers is therefore   7 + 2= 
  7 + 2 = 9

At exactly what time past 6:00 will the minute and hour hands of an accurate working clock be precisely perpendicular to each other for the first time? Choose the correct choice from the following choices:  A) 20 13/21 minutes past 7:00  B) 20 13/17 minutes past 7:00  C) 21 9/11 minutes past 6:00  D) 21 9/11 minutes past 7:00  E) 22 4/9 minutes past 7:00

Solution: 5.5 is the angle between minute n hour, this is what I was taught...so shouldn't it be solve by dividing 90 with 5.5?   That would have been the case if your initial difference between the hour and the minute hand was = 0 degrees or in other words, both minute and hour hands were at the same location. But as per the question, you are asked for time AFTER 6:00. At 6:00, the angle between the hour and the minute hand is 210 degrees. you need to take this into account as well.   So in order for the difference to decrease to 90 degrees, the minute hand must eat away this difference of   210-90= 
  210-90 = 120
120 degree at the rate of 5.5 degrees per minute ---> 120/5.5= 21 9/11 minutes.   Thus, 21 9/11 minutes past 6:00 is the correct answer.

Two trains of equal lengths take 10 sec and 12 sec respectively to cross a telegraph post. If the length of each train be 120 m, in what time will they cross other travelling in opposite direction?  Select
A) 11 sec
B) 12 sec
C) 17 sec
D) 21 sec
E) 23 sec

Solution: Speed of the first train = 120/10= 
120/10 = 12
12 m/sec.   Speed of the second train= 120/12= 
120/12 = 10
10 m/sec.   Relative speed= 12 + 10= 
12 + 10 = 22
22 m/sec.   Required time= (120 + 120)/22 = 11 sec.   11 secnswer: 11 sec

Find how many positive integers less than 10,000 are there suchthat the sum of the digits of the no. is divisible by 3?  Choose the correct answer: A) 1256 B) 2354 C) 2678 D) 3334 E) 3568

Solution: If sum of the digits is divisible by 3, the number is divisible by 3.   Therefore, required number of non-negative integers is equal to count of numbers less than 10,000 which are divisible by 3.   Such numbers are (3, 6, 9, ... , 9999) (arithmetic progression with first term=3, last term=9999, common difference=3).   Count of such numbers =   9999   3   =   3333   99993=3333   But zero is also divisible by 3.   This makes our total count 3334   3334

A) 1/16
B) 1/128
C) 1/8
D) 1/4
E) 1/2

Solution: TTTTTTTT case --> P = (1/2)^8 = 1/256   HHHHHHHH case --> P = (1/2)^8 = 1/256   P(TTTTTTTT or HHHHHHHH) = 1/8 + 1/8 = 1/128   Answer: 1/128
