Just check the options. If she bought 10 white sharpeners at Rs.6 per piece, She has spent Rs.60 already. And with the remaining Rs.40, she bought 8 brown sharpeners at 40/8 = Rs.5 which is Rs.1 less than White sharpener.

• 👉 Jake can dig a well in 16 days. Paul can dig the same well in 24 days. Jake, Paul and Hari together dig the well in 8 days. Hari alone can dig the well in__

1. 96 days 
2. 48 days  
3. 24 days  
4. 32 days

Simple one. Let the total work to be done is 48 meters. Now Jake can dig 3 mts, Paul can dig 2 mts a day. Now all of them combined dug in 8 days so per day they dug 48/8 = 6 mts. So Of these 8 mts, Hari capacity is 1 mt.  So he takes 48 /1 = 48 days to complete the digging job.

• 👉 The fourteen digits of a credit card are to be written in the boxes. XXX7XXXYXXX8XX. If the sum of every three consecutive digits is 18, then the value of Y is___

1.  3  
2.  2 
3.  1 
4. Can not be determined. 

Let us assume rightmost two squares are a , b  Then Sum of all the squares = 18 x 4 + a + b..........(1)  Also Sum of the squares before 7 = 18
Sum of the squares between 7, y = 18  and sum of the squares between y , 8 = 18  So Sum of the 14 squares = 18 + 7 + 18 + y + 18 + 8 + a + b………... (2)  Equating (1) and (2) we get y = 3

• 👉 On a 26 question test, five points were deducted for each wrong answer and eight points were added for each correct answer. If all the questions were answered, how many were correct, if the score was zero?

1. 10 
2. 12  
3. 11
4. 13

Take options and check. If 10 are correct, his score is 10 x 8 = 80. But 16 are wrong. So total negative marking is 16 x 5 = 80. So the final score is zero.

• 👉 Mark told John "If you give me half your money I will have Rs.75. John said, "if you give me one third of your money, I will have Rs.75/­ How much money did John have?

1.  45  
2.  60
3.  48  
4.  37.5 

Let the money with Mark and John are M and J respectively.  Now  M + J/2 = 75  M/3 + J = 75  Solving we get M = 45, and J = 60.

• 👉 2ab5 is a four digit number divisible by 25. If a number formed from the two digits ab is a multiple of 13, then ab is__

1. 52 
2. 45 
3. 10
4. 25 

For a number to be divisible by 25, the last two digits of that number should be divisible by 25. So b must be either 2 or 7  it is given that ab must be divisible by 13 and in the options only 52 is divisible by 13.

• 👉 If f(f(n))+f(n)=2n+3 and f(0)=1, what is the value of f(2012)?

1. 2011 
2. 2012
3. 2013  
4. 4095

Put n = 0  Then f(f(0))+f(0) = 2(0) + 3 â?? f(1) + 1 = 3 â?? f(1) = 2  Put n = 1  f(f(1)) + f(1) = 2(1) + 3 â?? f(2) + 2 = 5 â??f(2) = 3  Put n = 2  f(f(2)) + f(2) = 2(2) + 3 â?? f(3) + 3 = 7 â?? f(3) = 4 
f(2012) = 2013

• 👉 If 5+3+2=151022, 9+2+4=183652, then 7+2+5=?

1. 143547  
2. 143548  
3. 143557  
4. 143558 

If the given number is a + b + c then a.b | a.c | a.b + a.c ­ b  5+3+2 = 5.3 | 5.2| 5.3 + 5.2 ­ 3 = 151022  9+2+4 = 9.2 | 9.4 | 9.2 + 9.4 ­ 2 = 183652  7+2+5= 7.2 | 7.5 | 7.2 + 7.5 ­ 2 = 143547

• 👉 Given that 0 < a < b < c < d, which of the following the largest?

1. (c+d) / (a+b) 
2. (a+d) / (b+c)  
3. (b+c) / (a+d)  
4. (b+d) / (a+c)

Take a = 1, b = 2, c = 3, d = 4.

• 👉 A man has a job, which requires him to work 8 straight days and rest on the ninth day. If he started work on Monday, find the day of the week on which he gets his 12th rest day?

1. Thursday  
2. Tuesday  
3. Wednesday  
4. Friday

He works for 8 days and takes rest on the 9th day. So On the 12th rest day, there are 9 x 12 = 108 days passed. Number of odd days = (108 ­ 1) / 7 = 107 / 7 = 2. So the 12th rest day is wednesday.
