Solutions

1.             Ans: C
By the rules of divisibility, we know that any number is divisible by 8, if the last three digits of the number  is also divisible by 8.
In the given number last three digits are 354.  So, the remainder is 2.

5.             Ans: B
                                Let number of One-rupee coins = 2K
                                Number of 50 paise coins = 3K
                                Number of 25 paise coins = 4K
                          
                         
                          K = 48
                           Number of 50 paise coins = 3K = 144.

6.             Ans: B
                                Let the C. P. be Rs. X
                           If loss is 19%, then the S.P. would have been
          x - 19% of  x, (i. e)
                            of
                          36 x = 16,200

7.             Ans: B
                                Given:  8 Women = 6 Men = 12 Boys
                           12 Men + 12 Women + 12 Boys
                                = 12 Men + 9 Men + 6 Men = 27 Men
                We have,
                                , , ,
                                , , ,
                            
                         
                           days (or)  days.

8.             Ans: A
                                Let takes ‘t’ minutes to full the tank.
                                Then,
                               
                          t = 4 min.

9.             Ans: C
                                Let the speed of train ‘C’ be X km/hr.
At 9 p.m., the train ‘A’ will have covered a speed of 180 km.  For trains A and B relative speed
, distance = 180 km.
                           Time when they meet =
                               
                               

Mumbai
 

Delhi
 



For trains A and C relative speed = (60 + x), distance = 1080 km
                          
                           x = 120 km/hr.

10.          Ans: D
                                In a mixture of 1000 ml, milk : water = 3 : 1
                                Hence, milk = 750 ml and water = 250 ml
                                A 250 ml of 3 : 2 solution contains 150 ml milk and 100 ml water.
                                Total milk = 900 ml, total water = 350 ml.
                                After using 250 ml to make curd milk used =
                                Pure milk left = .

12.          Ans: C
                (a)           60% on food , which is correct.
                (b)           1/4th of money = 25% on other items, which is correct.
                (c)           5% on light and fuel so,  is incorrect.
                (d)           10% on cloth , which is there on the graph.

13.          Ans: D
                                A is the daughter of B means A is the sister of the son (say D) of B i.e., .

14.          Ans: C
                                We have:  A < B,   C < D,   B < C and   E < A
                                So, the sequence becomes
                                Clearly, child ‘D’ is the most intelligent.

15.          Ans : D
                                The movements of Rasik from A to F are as shown figure

F1.jpg
Since CD = AB + EF, So F lies in lin with A
Rasik’s distance from original position A
= AF = (AG + GF)
= (BC + DE) = (30 + 15) m = 45 m
Also F lies to the east of A.

16.          Ans: C
P = 4 and T – P = 5  T = 9
T – N = 3 and T = 9  N – 6

17.          Ans: C
Three persons A, B, C can be arranged in a queue in six different ways i. e., ABC, CBA, CAB, BCA. ACB but since there are only 3 persons ahead of C, so C should be in front of the queue. Thus, there are only two possible arrangements (i.e) CBA and CAB . We may consider the two cases as under :

CASE I:
                               
Clearly,  number of persons in the queue
= (3 + 1 + 8 + 1 + 5 + 1 + 21) = 40




CASE II:
                                               

               
                                                                               
                               
Number of persons between A and  C
                                =
                                Clearly, number of persons in the queue
                                = (3 + 1 + 2 + 1 + 21) = 28.
                                Now, 28 < 40.  So, 28 is the minimum number of persons in the queue.

18.          Ans: C
                                The sum of numbers in the first, second, third, - - - - - - 
Columns from the series  4, 9, 16, - - - - - - - -
                i.e.,         
                                Let the missing number be X
                                Then, 2 + 10 + x = 25
                          .

19.          Ans: C
Here, the number 2 appears in three dice, namely (i), (ii), and (iv).  In these dice, we observe
that the numbers 2, 4, 1 and 6 appear adjacent to 3.  So, none of these numbers can be present opposite 2.  The only number left is 5.
                                Hence, 5 is present on the face opposite 2.
                           The answer is (C)
_____________________________________________________________________________________________________
20.          Ans: A
                                All cups are glasses.  Some glasses are bowls
                                Since the middle term ‘glasses’ is not distributed even one in the premises, no definite
        conclusion follows.
                                Some glasses are bowls.  No bowl is a plate.
                                Since one premise is particular and the other negative, the conclusion must be particular negative and
        should not contain the middle term.  So, it follows that some glasses are not plates.
