- 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
- 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.
- 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.
- 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
- 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
- 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
- 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

- 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
- 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
- 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
- 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)
- 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
- 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
