1). c)  2). d)  3). c)  4). b)  5). c)  6). c)  7). c)  8). d)  9). a)  10). a) 
1).1 st class : Total Hand shakes = 24 × 23 /2 = 12 × 23 =276
     2nd class :Total Hand shakes =32 × 31 / 2 = 16 × 31 = 496
Difference =220
Answer : c
2).consider the price as 100
A = 100 × 0.9 × 0.8 × 0.7 =50.4
B = 100 × 0.8 × 0.8 × 0.8=51.2
C = 100 × 0.85 × 0.85 × 0.85 ×0.85 ~ =52.2
D = 100 × 0.8 × 0.6 =48
We see that the maximum discount of 52% (100-48) is on D, which is the best for a customer.
Answer : d
3).Work done by A and B in one day = 1/11 + 1/20 =31/220
Work done by A and C in one day = 1/11 + 1/55 =6/55
Work done in 2 days = 31 /220+6/55=55/220 = ¼
Hence, 1/4 of the work is done in 2 days
Hence, it takes 8 days to finish the work
Answer : c
4).Radius = 70m, So circumference = 2 × (22/7) × 70 =440m
Relative speed = 10 +20 = 30m/s
They will meet everytime at the starting point when the distance covered by both put together is a multiple of 440
LCM of (440,30) = 44 × 30
So, they will meet at starting point every 44 seconds.
In 30minutes, they will meet =1800/44 =40.9
So they will meet 40 times (we need to ignore the decimal part).
Answer : b
5). Let the age of Ram be R, brother be B
And (R + 9 ) =1.5(B + 9)
3B + 9 =1.5B + 13.5
1.5B =4.5 or B = 3 years R= 9 years.
Father current age = 4R(Since father is 3 times older than Ram, his age is R + 3 R, and not 3R)
Father age when Ram is 1.5 times the age of his brother = 4R + 9 = 45.
Answer : c
6). from statement I :
Let the price of product Q be ‘P’
Then the price of product R is 4P
From Statement II:
Cost of product Q =2
Cost of product R=5
Therefore,
Profit percentage of product Q = (P-2 ) × 100/2 =50(P-2)=50P – 100
Profit percentage of product R = (4P -5) × 100/5=20(4P-5)=80P-100
Hence, product R is more profitable.
Both statements are required to answer the question
7).From both statement I and II:
Let the number of chocolates received by child older than 5 years be x and that of for child than 5 years or younger be y
Therefore,
5x + 6 y = 43
Since x and y has to be natural numbers, the solution for the above equation will be x=5 and y=3
Hence, 5 children are older than 5 years
Answer : c
8). Let the radius of the circle be r units
From statement 1:
[πr^2]/ [ 2 πr ] > 7 or r > 14
From statement II:
Hence, r can be 15 or 16 units
Answer : d
9).Let the current ages of X and Y be a and b respectively
From the question:
From statement I:
Therefore, a = 3(a-17-3)
Hence, X is 30 years old
From statement II:
a + 9 = 3b
Substituting this in first equation,
Hence, no result
Therefore, statement I alone is sufficient
10). From statement I :
(x2 +x) should be less than 100 and greater than 50
This is possible only for 3 numbers i.e.7,8,9
72 + 7 =56
82 + 8 = 72
92 + 9 = 90
But only 7 is prime number. Hence,x=7
From statement II:
The value of x can 5 or 7, since both 53 and 73 is a three digit number
Hence, only statement I alone is sufficient to answer the question
Answer : a
