Aptitude practice questions for sbi clerk 2018 part 1

1 )  22 , 10 , 8 , 12 , 40 , ?
Ans :


Note : Whenever you will find the second number is near of half of first number and third number is near of second number . Then , that series is based on  Half Pattern Series.


Whenever your series is Half pattern . as per the name it is required we have to multiply with 0.5

22 x 0.5 – 1 = 10

10 x 1 – 2  = 8

8 x 2 – 4 = 12

12 x 4 – 8 = 40

40 x 8 – 16 = 304

2 ) 8, 4.5, 5.5, 13, 56, ?

Ans :

Note : If you will find any decimal number in number series . Answer will be multiply by * 0.5 or 1.5

8 x 0.5 + 0.5 = 4.5

4.5 x 1 + 1 = 5.5

5.5 x 2 + 2 = 13

13 x 4 + 4 = 56

56 x 8 + 8 = 456

 
3) 8, 4, 4, 6, 12, .....?

Ans :

Note : If the same numbers are exist in the question. Maximum answer will follows the Divisible method.

4÷8 = 0.5

4÷4 = 1

6÷4 = 1.5

12÷6 = 2

x÷12 = 2.5

x = 12*2.5

x = 30

 

4 )

6, 3, 3, 6, 24, ?

Ans :

Note : If the same numbers are exist in the question. Maximum answer will follows the Divisible method.

 

6 ✕ 0.5 = 3

3 ✕ 1 = 3

3 ✕ 2 = 6

6 ✕ 4 = 24

24 ✕ 8 = 112

5)
Find the value of 3(1/5) +6(8/7)-4(6/5)

Ans:

        Write the above question as below                                      {x(a/b) = x+(a/b)}

                     3+6-4+(1/5)+(8/7)-(6/5)

                      5+(8/7)

                     we can write 6+(8/7) as 6(8/7)

6) Find the value of 50 % of 680 + 20 % of 70

Ans :
100 % of 680 is 680
50 % 0f 680 is 340
10 % of 70 is 7
20 % of 70 is =10%+10% = 20% i.e 14

50 % of 680 + 20 % of 70 = 340+14 = 354

7)If a man buys a TV for 3500 and he sold it for 25% profit. What is his selling Price ?


Ans:                  Here CP = 3500


                                  Profit % = 25 %

                                  SP = 125 % of 3500

                                  SP= (125*3500)/100

                                   SP= 4375.

8)If A's salary is 20% less than B's Salary, by how much percent is B 's salary more than A's?

Ans:                                 

                            

A is x% less than B , then B is more than A by    

                           

(x/(100-x)) *100 %

here x is 20 %

(20/80)*100 %

(1/4)*100 %

=25%

Order and Ranking For SBI Clerk prelims

In this session we need to learn one main important formula to find the answers for order and ranking. i. e


T = L + R -1


Here T = Total number of persons
        L= Rank from the Left side
        R= Rank from the Right side


This formula is applicable only when we are saying about only one person in a row .

Ex: In a Row of 30 students . Raju is 14th from the Right . Then what is the Raju position from left ?


                     T= R+L -1
                   30= 14+L-1
                   L= 30-13 =17


Ex: In a Row  f children's ammu is sitting 12th from the right and 17th from the left . Then what is the total number of children's in a row?


                    T= 12+17-1
                    T=28
Ex: In a row of girls , swathi is 15^th from the Left and Ravi is 23^rd from the Right . If their positions are interchanged, then Swathi becomes 18^th from the Left. Then at what position will Ravi from the right?
Ans :     

Ex: In a row of 26th student's  Reka is 12th from the Left and Haritha is 7th from the right. Divya is sitting exactly between then. Then what will be the Divya position from Right and Left?


Ans :

SBI Clerk 2018 Number Series Tricks

We will get questions on numbers series based on below five methods:


1) Series based on Square or Cube: In this case we will find the difference of the numbers and we will get the answers

 

Ex : 31, 33, 40, 68, 131, ?

Ans :

31 + (1³ + 1) = 31 + 2 = 33
33 + (2³ - 1) = 33 + 7 = 40
40 + (3³ + 1) = 40 + 28 = 68
68 + (4³ - 1) = 68 + 63 = 131
131 + (5³ + 1) = 131 + 126 = 257

 

Ex: 11        13        20        48        111        ?( Practice : ans :237)

 

 

       

 

2) Series based on Decimal number: If you will find any decimal number in the question . Answer will be multiply by * 0.5 or 1.5

 

Ex : i) 12, 6.5, 7.5, 17, 72, ?

 

Ans :

12x 0.5 + 0.5 = 6.5
6.5 x 1 + 1 = 7.5
7.5 x 2 + 2 = 17
17 x 4 + 4 = 72
72 x 8 + 8 = 584

 

Ex : 6        3.5        4.5        11        48        ? ( Practice : ans :392)

 



3) Completely Divisible series : If the same numbers are exist in the question. Maximum answer will follows the Divisible method.

 

Ex : 12  , 12  ,  18  , 45  , 180  ,   ?

 

Ans :

 

12 /12 =1

18/12 = 1.5

45/18 = 2.5

180/45 =4

x/180 = 6

x = 180*6=1080

 

 here you will get question like how we have written x/180 is 6

see the difference from top from 1 to 1.5 is 0.5

                                            from 1.5 to 2.5 is 1

                                            from 2.5 to 4 is 1.5

                                     we need to get next difference is 2 so from 4 to 6 is 2

 



4) Half Pattern series : Whenever you will find the second number is near of half of first number and third number is near of second number . Then , that series is based on  Half Pattern Series.

Whenever your series is Half pattern . as per the name it is required we have to multiply with 0.5

 

Ex : 70     ,       40     ,       50     ,   90         ,  200   ,        ?

 

Ans :

(70 *0.5 )+5 = 40

(40*1 )+10 =50

(50*1.5)+15 =90

(90*2)+20 = 200

(200*2.5)+25 =525

 



5) Series based on Multiplication :. If any series you will find that number is suddenly increased bulk . That series is based on multiplication.

 

Ex : 3, 4, 10, 33, 136, ?

 

Ans :

x 1 + 1 = 4
4 x 2 + 2 = 10
10 x 3 + 3 = 33
33 x 4 + 4 = 136
136 x 5 + 5 = 685

 

 Ex: Practice :

 

6         16         45         184         917         ?

 

Ans :5508

Some Important models on Simplifications problems

In this article we are going to tell tricks for some simplification problems which you will get in bank exams every time.
Example :
Find the value of 115 % of 430 + 36% 0f 170.
Ans:
Write 115 % as (100+10+5) %                    36% we can write as (30+6)%
          100 % 0f 430 means 430                                30% of 170 means 51
           10 % of 430 means 43                                  1% means 1.7
            5% means 43/2 i.e 21.5                                 6% means 6*1.7=10.2
 add above 3 values 430
                                   43                                         add both values i.e (30+6)% =51+10.2=61.2
                                   21.5                                                                
                                 ----------
                                  494.5


               115 % of 430 + 36% 0f 170 = 494.5+61.2 = 555.7


Example :
Find the value of 3(1/2) +5(3/4)-2(7/8)
Ans:
        Write the above question as below                                      {x(a/b) = x+(a/b)}
                     3+5-2+(1/2)+(3/4)-(7/8)
                      6+(3/8)
                     we can write 6+(3/8) as 6(3/8)


Example :Evaluate



Ans:

In the above question 34^2 - 56^2

 we can write as (34+56)(34-56)

                               (34+56)(34-56)/(34+56)

 answer will be 34-56 i.e -22

Note :

we have to learn some formulas for this type of questions .

Example: find the value of  x .
                  

6²   ×  (6⁵)⁴ ÷ 6³  ₌  6^x+2  

Ans:

6²   ×  (6⁵)⁴ ÷ 6³  ₌  6^x+2  

6²×6²⁰ ÷6³ = 6^x+2

6²⁺²⁰÷6³ = 6^x+2

6²²÷6³=6^x+2

6^22-3=6^x+2

6¹⁹=6^x+2

X+2=19

X=19-2

X=17

Note: We have to learn some formulas to solve the above model questions . that are

X^m . Xⁿ  =  X^m+n

X^m ÷ Xⁿ  = X^m-n

X^m = Xⁿ  --------à    m=n
