14. The sum of two numbers is 22. Five times one number is equal to 6 times the other. The bigger of the two numbers is-

(A) 10

(B) 12

(C) 15

(D) 16

Answer: (B) 12

Solution:

Let the Bigger number is x and smaller is 22-x

ATQ,

5x = 6(22-x)

Or, 11x = 132

Or, x = 12

15. Q is as much younger than R as he is older than T. If the sum of ages of R and T is 50years, what is definitely the difference between R and Q’s age?

(A) 1 years

(B) 25years

(C) 2 years

(D) Data inadequate

Answer:

Solution:

R – Q = Q – T

(R + T) = 2Q

Now given that, (R + T) = 50

So, 50 = 2Q and therefore Q = 25.

Question is (R – Q) = ?

Here we know the value(age) of Q (25), but we don’t know the age of R.

Therefore, (R-Q) cannot be determined.

16. At an election involving two candidates, 68 votes were declared invalid. The winning candidates secure 52% and wins by 98 votes. The total numbers of vote polled-

(A) 2382

(B) 2450

(C) 2518

(D) None of these

Answer: (C) 2518

Solution:

Let the number of valid votes be x.

ATQ,

52% of x – 48% of x = 98

Or, 4% of x = 98

Or, 4/100 × x = 98

Or, x = 98 × 25 = 2450.

Invalid votes = 68

∴Total number of votes polled = (2450 + 68) = 2518.

17. If 5% more is gained by selling an article for Tk.350 than by selling it for Tk.340, the cost of the article is-

(A) Tk.50

(B) Tk.160

(C) Tk.200

(D) Tk.225

Answer:(C) Tk.200

Solution:

Let the cost =x tk

So, first gain= (340-x)tk

Second gain=(350-x)tk

So, difference=(350-x)-(340-x)tk=10 tk

Here, 5%=10tk

So,100%=200tk

18. x varies inversely as square of y. Given that y=2 for x=1. The value of x for y = 6 will be equal is-

(A) 3

(B) 9

(C) 1/5

(D) 1/9

Answer:

Solution:

x α 1/y2 Inversely proportional

or, x = k/y² [ k is a constant ]

y = 2 for x = 1

So, 1 = k/2²

Or, k = 4

So, for y = 6

x = 4/6² = 4/36

Or, x = 1/9

19. If 9 examiners can examine a certain number of answer books in 12 days, working 5 hours a day; for how many hours a day would 4 examiners have to work in order to examine twice the number of answer book is 30 days?

(A) 3

(B) 8

(C) 9

(D) 10

Answer: (C) 9

Solution:

Let, required time x hour/day

30 days= 30x hour

At first stage, 12 days = 60 hour

4 examiners examines in=60 × 9/4 = 135 hours

So, time needed to examine the double answer books is =

135 × 2 = 270 hour

Here, 30x = 270

So, x=9

20. If a person walk at 14km/hr instead of 10km/hr, he would walked 20 km more. The actual distance travelled by him is-

(A) 50km

(B) 56km

(C) 70km

(D) 80km

Answer: (A) 50km

Solution:

Let the actual distance travelled = x km

ATQ,

x/10 = (x + 20)/14

Or, 14x = 10x + 200

Or, x = 50 km

21. What will be the difference between simple and compound interest at 10% per annum on a sum of Tk.1000 after 4 years?

(A) Tk. 31

(B) Tk. 32.10

(C) Tk. 40.40

(D) Tk. 64.10

Answer: (D) Tk. 64.10

Solution:

At simple interest,

tk 1000 after 4 years incurs = 10 x1000x4/100=400 tk

at compound interest,

c=p(1+r)ⁿ=1000(1+10/100)⁴= 1464.1 tk

So, the amount incurred= 1464.1-1000 = 464.1 tk

Difference = (464.1-400)tk = 64.1 tk

22. The sum of two numbers is 12 and their product is 35. What is the sum of reciprocals of these numbers?

(A) 12/35

(B) 1/35

(C) 35/8

(D) 7/32

Answer: (A) 12/35

Solution:

Let a and b are the numbers.

Then a+b = 12 and ab = 35.

the sum of reciprocals,

1/a + 1/b

= (a+b)/ab

= 12/35

23. The least number of 5 digits which is exactly divisible by 12, 15, and 18 is –

(A) 10010

(B) 10015

(C) 10020

(D) 10080

Answer: (D) 10080

Solution:

Smallest five-digit number = 10000

LCM (12, 15, 18) = 180.

On dividing 10000 by 180, remainder = 100

Required number = 10000 + (180 – 100) = 10080

24. A boy multiplied 423 by a number and obtained 65589 as his answer. If both the fives in the answer are wrong and all other figures are correct, the correct answer is-

(A) 60489

(B) 62189

(C) 61189

(D) 62389

Answer: (A) 60489

Solution:

423 = 3 × 3 × 47

So, the required number must be divisible by each one of 3 and 47.

Now start with the smaller number 3.

60489 = 6+4+8+9 = 27 (divisible by 3)

62189 = 26 (Not divisible by 3)

61189 = 26 (Not divisible by 3)

62389 = 28 (Not divisible by 3)

25. The least perfect square, which is divisible by each 21, 36 and 66 is –

(A) 213444

(B) 214344

(C) 214434

(D) 231444

Answer: (A) 213444

Solution:

L.C.M. of 21, 36, 66 = 2772.

Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11

To make it a perfect square, it must be multiplied by 7 x 11

So, required number

= 2² x 3² x 7² x 11²

= 213444

26. The average of five consecutive odd numbers is 61. What is the difference between the highest and lowest number?

(A) 2

(B) 5

(C) 8

(D) None of these

Answer: (C) 8

Solution:

As the average is 61, it is the middle of the 5 odd numbers.

So, the numbers are 57, 59, 61, 63, 65.

The difference between the highest and lowest number = 65 – 57 = 8
