#### Question No 1

John has 30 Marbles ,18 of which are red and 12 of which are blue. Jane has 20 Marbles all of them either red or blue. If the ratio of the red Marbles to the blue Marbles is the same for both John and jane, then John  has how many more blue marbles than Jane?

Solution!
John marble ratio:
18 :12
3: 2
Jane Marbles are also with the same ratio as john.
Red: blue.    total

3:       2.       20
3 X + 2 x = 20 = > 5 x = 20= >X = 4
2 X = 2( 4 )= 8 blue marbles
John have: 12 - 8 = 4 blue Marbles than jane

#### Question No 12

In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct option
C B _ _ D _ B A B C C B _  _ 1 2 4 3  _ _ ? ? ? ? a _ a b _ c _ b _ _ _ _

Solution!
Comparing position of capital letters, numbers and small letters, as we find:
a corresponds to C and 1 corresponds to a. So a and 1 corresponds to C.
b corresponds to A and 2 corresponds to b. So b and 2 corresponds to A.
Also, 4 corresponds to D.
So the remaining number i.e. 3 corresponds to B, So BCCB corresponds to 3, 1, 1, 3.

#### Question No 13

In a 100m race a once with a speed of 1.66 metre per second. If a give a start of 4 minute to be and still beats him by 12 seconds. What is the speed of B?

Solution!
Time taken by a to cover hundred metres =60 seconds
Since a gives a start of 4 minutes then time taken by b =72 seconds
B takes 72 second to cover 96 meters
speed of B =96 / 8
72 = 1.33 meter per second.

#### Question No 16

A, B, C, D and E play a game of cards. A says to B, "If you give me 3 cards, you will have as many as I have at this moment while if D takes 5 cards from you, he will have as many as E has." A and C together have twice as many cards as E has. B and D together also have the same number of cards as A and C taken together. If together they have 150 cards, how many cards has C got ?

Solution!
Clearly, we have :
A = B - 3 ...(i)
D + 5 = E ...(ii)
A+C = 2E ...(iii)
B + D = A+C = 2E ...(iv)
A+B + C + D + E=150 ...(v)
From (iii), (iv) and (v), we get: 5E = 150 or E = 30.
Putting E = 30 in (ii), we get: D = 25.
Putting E = 30 and D = 25 in (iv), we get: B = 35.
Putting B = 35 in (i), we get: A = 32.
Putting A = 32 and E = 30 in (iii), we get: C = 28.

#### Question No 17

3251 + 587 + 369 - ? = 3007

Solution!
3251+ 587 + 369 = 4207
