IA Paper Answers and Questions
Q1.If L stands for +, M stands for -, N stands for x, P stands for / then 15N 10 L 30 P 6 M 8 =
(1) 145 (2)147 (3)146 (4) 148
Solution.
Step1) Change the equation into correct format which is
15 x 10 + 30 / 6 - 8
Step2) Use BODMAS that is Division first ,than multiplication , than addition and afterwards subtraction.
Step3) 15 x 10 + 5 - 8 (Division)
Step4) 150 + 5 - 8 ( Multiplication)
Step5) 155 - 8 (Addition)
Step6 147
That is (2)
Q2. If 20-10 means 2; 8 / 4 means 32; 6 x2 means 8, then 100 -10 x 4 /6 equals
(1) 32 (2) 34 (3)36 (4) 35
Step1) Try to figure out what the above equations signifies.
That is what 20-10 = 2 signifies, what mathematical operator we should use between these two number so we get the value 2? Only division(/) operator which gives us 2 at RHS. So - => / ( minus sign implies division).
Similarly / => x and x => + respectively.
So,
Step2) 100 -10 x 4/6 changes into 100 / 10 + 4 x 6
Step3) 10 +4 x 6
Step4) 10 + 24
Step5) 34
That is (2)
Q3. Five persons A,B,C,D and E are sitting in a row. Who is sitting in the middle if: (i) B is between E and C, (ii) B is to the right of C (iii) D is between A and E
(1) D (2) B (3) E (4) A
Solution.
To find out middle person, we need to write each person position on paper according to the information given to us.
Step1). E B C ( B is between E and C)
Step2). C B E ( B is right of C and B is between E and C)
Step3). C B E D A ( B is right of C , B is between E and C and D is between A and E)
So middle term is E.
So Answer is (3) E.

So middle term is E.
So Answer is (3) E.
Q4. What is the number of squares in the following figure?
| 1 | 2 | 3 |
| 4 | 5 | 6 |
| 7 | 8 | 9 |
Solution:
We will try to solve this problem by canceling least possible option for eg. By putting numbers inside the square, we can make out one conclusion that squares can't be less than 9.
Step1. (1 2 4 5) makes one more square so total squares become 9 + 1= 10 so (3) option is incorrect
Step2.( Similarly 4 5 7 8) makes one square and total becomes 11 , so we can cancel (2) nd option too.
Step3. Now there is only two options left, by assumption I can say that there are only 14 squares possible , but if you want to count you can.
So Answer is 14 that is (4)
Q5. A is three year older to B and 3 years younger to C, B and D are twins. How many years older is C to D?
(1) 2 (2) 3 (3) 6 (4) 12
Solution:
Write equations from the information given above:
A = 3 + B --> Eq 1
C = A + 3 --> Eq 2
B = D
Find equation between C and D
Step 1) A = 3 + D ( we know B = D , so we replace B with D)
Step 2) C = 3 + D + 3 ( Replace A with Eq 1)
Step 3) C = 6 + D
So, we can conclude that C is 6 years older than D that is (3).
Q6. Find the number which when added to itself 13 times gives 112
(1) 7 (2) 8 (3) 9 (4) 11
Solution.
Let x be the number , which is added to itself 13 times that is 13x.
x + 13x = 112
x = 112/14 = 8
That is option (2).
Q7.(A)Rahul at present is 25 years younger to his mother.
(B) Rahul brother, who was born in 1964, is 35 years younger to his mother.
In which year year was Rahul Born?
(1) (A) alone is sufficient while (B) alone is not sufficient
(2) (B) alone is sufficient while (A) alone is not sufficient
(3) Either (A) or (B) is sufficient
(4) Both (A) and (B) are sufficient
Solution:
From A we know that Rahul is 25 years younger to his mother but with this information we can't deduce Rahul's age.
From B we can find out the born year of Rahul's mother but still this information can't be used to find Rahul's age, for that we need first statement.
So Answer is (4) Both (A) and (B) are sufficient.
Q8. (A) One fourth of the weight of each pole is 5 Kg.
(B)The total weight of three poles is 20 Kg more than the total weight of two poles.
What will be the total weight of 10 poles, each of same weight ?
(1) (A) alone is sufficient while (B) alone is not sufficient
(2) (B) alone is sufficient while (A) alone is not sufficient
(3) Either (A) or (B) is sufficient
(4) Both (A) and (B) are sufficient
Step 3) C = 6 + D
So, we can conclude that C is 6 years older than D that is (3).
Q6. Find the number which when added to itself 13 times gives 112
(1) 7 (2) 8 (3) 9 (4) 11
Solution.
Let x be the number , which is added to itself 13 times that is 13x.
x + 13x = 112
x = 112/14 = 8
That is option (2).
Q7.(A)Rahul at present is 25 years younger to his mother.
(B) Rahul brother, who was born in 1964, is 35 years younger to his mother.
In which year year was Rahul Born?
(1) (A) alone is sufficient while (B) alone is not sufficient
(2) (B) alone is sufficient while (A) alone is not sufficient
(3) Either (A) or (B) is sufficient
(4) Both (A) and (B) are sufficient
Solution:
From A we know that Rahul is 25 years younger to his mother but with this information we can't deduce Rahul's age.
From B we can find out the born year of Rahul's mother but still this information can't be used to find Rahul's age, for that we need first statement.
So Answer is (4) Both (A) and (B) are sufficient.
Q8. (A) One fourth of the weight of each pole is 5 Kg.
(B)The total weight of three poles is 20 Kg more than the total weight of two poles.
What will be the total weight of 10 poles, each of same weight ?
(1) (A) alone is sufficient while (B) alone is not sufficient
(2) (B) alone is sufficient while (A) alone is not sufficient
(3) Either (A) or (B) is sufficient
(4) Both (A) and (B) are sufficient
Solution. Lets weight of one pole is x and according to A 1/4 * x = 5 so x = 20 Kg.
and from B 3x = 20 + 2x which means x = 20 ,so total weight become 200 Kg.
So answer is (3) Either (A) or (B) is sufficient
