1. Rajesh writes a two digit number. He sees that the number exceeds 4 times the sum of its digits by 3. If the number is increased by 18, the result is the same as the number formed by reversing the digits. Find result or number.

a) 35

b) 42

c) 49

d) 57

Solution: Let the two digit number be xy.

4(x + y) +3 = 10x + y …….(1)

10x + y + 18 = 10 y + x ….(2)

Answering 1st equation we get 2x – y = 1 …..(3)

Answering 2nd equation we get y – x = 2 …..(4)

Answering 3 and 4, we get x = 3 and y = 5

2. a, b, c are non negative integers such that 28a+30b+31c = 365. a + b + c = ?

a) Greater than 14

b) less than or equal to 11

c) 13

d) 12

In a calender,

Number of months with 28 days = 1

Number of months with 30 days = 4

Number of months with 31 days = 7

28 x 1 + 30 x 4 + 31 x 7 = 365

Here, a = 1, b = 4, c = 7.

a+b+c = 12

3. G can do a piece of work in 8 hours. P can do the same work in 10 hours, H can do the same work in 12 hours. G, P and H start the same work at 9 am, while G stops at 11 am, the remaining two complete the work. What time will the work complete?

a) 11.30 am

b) 12 noon

c) 12.30 pm

d) 1 pm

Let the total work = 120 units.

As G completes this entire work in 8 hours, his capacity is 15 units /hour

Similarly, the capacity of paul is 12 units / hour

the capacity of H is 10 units / hour

All 3 started at 9 am and worked upto 11 am. So total work done upto 11 am = 2 x (15 + 12 + 10) = 74

Remaining work = 120 – 74 = 46

Now this work is to be done by P and H. 46 / (12 + 10) = 2 hours (approx)

So work gets completed at 1 pm

4. If x^y denotes x raised to the power y, Find last two digits of (1141^3843) + (1961^4181)

a) 02

b) 82

c) 42

d) 22

Remember Any power raised above 1 is always equal to 1

To find the digit in the 10th place, we have to multiply, 10th digit in the base x unit digit in the power.

So the Last two digits of the given expression = 21 + 61 = 82

5. Jaggan can dig a well in 16 days. Pappu can dig a well in 24 days. Jaggan, Pappu, Humpty dig in 8 days. Humpty alone can dig the well in How many days?

a) 32

b) 48

c) 96

d) 24

Assume the total work = 48 units.

Capacity fo Jaggan = 48 / 16 = 3 units / day

Capacity of Pappu = 48 / 24 = 2 units / day

Capacity of Jaggan, Pappu, Humpty = 48 / 8 = 6 units / day

From the above capacity of Humpty = 6 – 2 – 3 = 1

So Humpty takes 48 / 1 days = 48 days to dig the well

6. If a lemon and apple together costs Rs.12, tomato and a lemon cost Rs.4 and an apple costs Rs.8 more than a lemon. What is the cost of lemon?

L + A = 12 …(1)

T + L = 4 …(2)

L + 8 = A

Taking 1 and 3, we get A = 10 and L = 2

7. 3 M and 4 A costs Rs.85. 5 A and 6 P costs 122. 6 M and 2 P costs Rs.144. What is the combined price of 1 A, 1 P, and 1 M.

a)Rs 37

b)Rs 39

c)Rs 35

d)Rs 36

Note: its not 144 but 114

3m + 4a = 85 ..(1)

5a + 6p = 122 ..(2)

6m + 2p = 114 ..(3)

(1) x 2 => 6m + 8a = 170

(3) => 6m + 2p = 114

Solving we get 8a – 2p = 56 ..(4)

(2) => 5a + 6p = 122

3 x (4) = 24a – 6p = 168

Solving we get a = 10, p = 12, m = 15

So a + p + m = 37

8. 3 committees are in one organisation , only 2 people are members of all 3 committee but every pair of committee has 3 members in common. what is the least possible number of members on any one committee?

(ii) If Jamun is eaten on Monday, Ladu should be eaten on friday.

(iii) Peda is eaten the day following the day of eating Jilebi

(iv) If Ladu eaten on tuesday, kaju should be eaten on monday

based on above,data Ladoo can be eaten on any day except

a) tuesday

b) monday

c) wednesday

d) friday

From the (iii) clue, peda must be eaten after jilebi. so Peda should not be eaten on monday.

10. If YWVSQ is 25 – 23 – 21 – 19 – 17, Then MKIGF

a) 13 – 11 – 8 – 7 – 6

b) 1 – 2-3-5-7

c) 9 – 8 – 7 – 6 – 5

d) 7 – 8 – 5 – 3

MKIGF = 13 – 11 – 9 – 7 – 6

Note: this is a dummy question. Dont answer these questions

11. Addition of 641 + 852 + 973 = 2456 is incorrect. What is the largest digit that can be changed to make the addition correct?

a) 5

b) 6

c) 4

d) 7

641

852

963

——

2466

largest among tens place is 7, so 7 should be replaced by 6 to get 2456

12. Value of a scooter depriciates in such a way that its value at the end of each year is 3/4th of its value at the beginning of the same year. If the initial value of scooter is 40,000, what is the value of the scooter at the end of 3 years.

a) 23125

b) 19000

c) 13435

d) 16875

value of the scooter at the end of the year = 40000×(34)3 = 16875

13. At the end of 1994, R was half as old as his grandmother. The sum of the years in which they were born is 3844. How old R was at the end of 1999

a) 48

b) 55

c) 49

d) 53

In 1994, Assume the ages of GM and R = 2k, k

then their birth years are 1994 – 2k, 1994 – k.

But given that sum of these years is 3844.

So 1994 – 2k + 1994 – k = 3844

K = 48

In 1999, the age of R is 48 + 5 = 53

14. When numbers are written in base b, we have 12 x 25 = 333, the value of b is?

a) 8

b) 6

c) None

d) 7

Let the base = b

So, (b+2)(2b+5) = (b+2)(2b+5)=3b2+3b+3

2b2+9b+10=3b2+3b+3

b2−6b−7=0

Solving we get b = 7 or -1

So b = 7

15. How many polynomials of degree >=1 satisfy f(x2)=[f(x)]2=f(f(x)

a) more than 2

b) 2

c) 0

d) 1

Let f(x) = x2

f(x2)=[x2]2=x4

(f(x))2=[x2]2=x4

f(f(x))=f(x2)=[x2]2=x4

Only 1

16. Figure shows an equilateral triangle of side of length 5 which is divided into several unit triangles. A valid path is a path from the triangle in the top row to the middle triangle in the bottom row such that the adjacent triangles in our path share a common edge and the path never travels up (from a lower row to a higher row) or revisits a triangle. An example is given below. How many such valid paths are there?

a) 120

b) 16

c) 23

d) 24

Sol:

Number of valid paths = (n-1) ! = (5-1)! = 24

17. In the question, A^B means, A raised to power B. If x*y^2*z < 0, then which one of the following statements must be true?

(i) xz < 0 (ii) z < 0 (iii) xyz < 0

a) (i) and (iii)

b) (iii) only

c) None

d) (i) only

As y^2 is always positive, x*y^2*z < 0 is possible only when xz < 0. Option d is correct.

18. The marked price of a coat was 40% less than the suggested retail price. Eesha purchased the coat for half the marked price at the fiftieth anniversary sale. What percentage less than the suggested retail price did Eesha pay?

a) 60

b) 20

c) 70

d) 30

Let the retail price is Rs.100. then market price is (100-40) % of 100 = 60. Eesha purchased the coat for half of this price. ie., 30 only. which is 70 less than the retail price. So Option C is correct.

As sources for TCS sample paper or sample papers of exams keep on changing so , some confusion may occur at times and we would request students to focus on solution of question not on whether this question was asked in july exam of TCS or Oct exam of TCS hence forth.
