## Must Attempt Quiz Before Exam For OSSSC RI, ARI, AMIN, SFS, ICDS Supervisor 2024

- If P(E) = 0.07, then what is the probability of ‘not E’?

(a) 0.93

(b) 0.95

(c) 0.89

(d) 0.90

Answer: (a) 0.93

Explanation: P(E) + P(not E) = 1

Since, P(E) = 0.05

So, P(not E) = 1 – P(E)

Or, P(not E) = 1 – 0.07

∴ P(not E) = 0.93 - A bag has 3 red balls and 5 green balls. If we take a ball from the bag, then what is the probability of getting red balls only?

(a) 3

(b) 8

(c) ⅜

(d) 8/3

Answer: (c) ⅜

Explanation: Number of red balls = 3

Number of green balls = 5

Total balls in bag = 3+5 = 8

Probability of getting red balls = number of red balls/total number of balls

= ⅜ - A bag has 5 white marbles, 8 red marbles and 4 purple marbles. If we take a marble randomly, then what is the probability of not getting purple marble?

(a) 0.5

(b) 0.66

(c) 0.08

(d) 0.77

Answer: (d) 0.77

Explanation: Total number of purple marbles = 4

Total number of marbles in bag = 5 + 8 + 4 = 17

Probability of getting purple marbles = 4/17

Hence, the probability of not getting purple marbles = 1-4/17 = 0.77 - Fifteen solid spheres are made by melting a solid metallic cone of base diameter 2cm and height 15cm. The radius of each sphere is:

(a) ½

(b) ¼

(c) 1/3√2

(d) 1/3√4

Answer: (d) 1/3√4

Explanation: Volume of 15 spheres = Volume of a cone

15 x (4/3) π r3 = ⅓ πr2h

5×4 π r3 = ⅓ π 12(15)

20r3 = 5

r3 = 5/20 = ¼

r = 1/3√4 - The radius of the top and bottom of a bucket of slant height 35 cm are 25 cm and 8 cm. The curved surface of the bucket is:

(a) 4000 sq.cm

(b) 3500 sq.cm

(c) 3630 sq.cm

(d) 3750 sq.cm

Answer: (c) 3630 sq.cm

Explanation: Curved surface of bucket = π(R1 + R2) x slant height (l)

Curved Surface = (22/7) x (25 + 8) x 35

CSA = 22 x 33 x 5 = 3630 sq.cm. - The area of the square that can be inscribed in a circle of radius 8 cm is

(a) 256 cm2

(b) 128 cm2

(c) 642 cm2

(d) 64 cm2

Answer: (b) 128 cm2

Explanation: Radius of circle = 8 cm

Diameter of circle = 16 cm = diagonal of the square

Let “a” be the triangle side, and the hypotenuse is 16 cm

Using Pythagoras theorem, we can write

162= a2+a2

256 = 2a2

a2= 256/2

a2= 128 = area of a square. - 11th term of the A.P. -3, -1/2, 2 …. Is

(a) 28

(b) 22

(c) -38

(d) -48

Answer: (b) 22

Explanation: A.P. = -3, -1/2, 2 …

First term a = – 3

Common difference, d = a2 − a1 = (-1/2) -(-3)

⇒(-1/2) + 3 = 5/2

Nth term;

an = a+(n−1)d

a11 = 3+(11-1)(5/2)

a11 = 3+(10)(5/2)

a11 = -3+25

a11 = 22 - The number of multiples of 4 between 10 and 250 is:

(a) 50

(b) 40

(c) 60

(d) 30

Answer: (c) 60

Explanation: The multiples of 4 after 10 are:

12, 16, 20, 24, …

So here, a = 12 and d = 4

Now, 250/4 gives remainder 2. Hence, 250 – 2 = 248 is divisible by 2.

12, 16, 20, 24, …, 248

So, nth term, an = 248

As we know,

an = a+(n−1)d

248 = 12+(n-1)×4

236/4 = n-1

59 = n-1

n = 60 - In an AP, if d = -4, n = 7, an = 4, then a is

(a) 6

(b) 7

(c) 20

(d) 28

Answer: (d) 28

Solution;

Given,

d = -4, n = 7, an = 4

We know that,

an = a + (n – 1)d

4 = a + (7 – 1)(-4)

4 = a + 6(-4)

4 = a – 24

⇒ a = 4 + 24 = 28 - The point which divides the line segment of points P(-1, 7) and (4, -3) in the ratio of 2:3 is:

(a) (-1, 3)

(b) (-1, -3)

(c) (1, -3)

(d) (1, 3)

Answer: (d) (1, 3)

Explanation: By section formula we know:

x = [(2 × 4) + (3 × (-1))]/(2 + 3) = (8 – 3)/5 = 1

y = [(2 × (-3)) + (3 × 7)]/(2 + 3) = (-6 + 21)/5 = 3

Hence, the required point is (1, 3). - Find the odd one out.

a) Figure A

b) Figure B

c) Figure C

d) Figure D

Answer: c

Explanation: Here, the figures present inside the box have even number of edges.

That is:

A ➔ 6 edges

B ➔ 4 edges

D ➔ 10 edges

But, in figure C the number of edges of the figure present inside the box is 3 (That is an odd number).

Hence, figure C is the answer. - Find the odd one out.

a) Dinar

b) Kwanza

c) Taka

d) Gaborone

Answer: d

Explanation: Here, Dinar is the currency of Kuwait, Kwanza is the currency of Angola and Taka is the currency of Bangladesh.

But Gaborone is not a currency of any country but it is a capital city of Botswana.

Hence, Gaborone is the answer. - In a certain code “STAMP” is written as “TVDQU”. How is “FLAME” written in that code?

a) SRLFE

b) JDKAL

c) GNDQJ

d) UDQKA

Answer: c

Explanation: Here, every letter of the word moves +n from its position where n is position of alphabet in the word.

i.e. for STAMP, S+1→T, T+2→V, A+3→D, M+4→Q, P→U.

Similarly, for FLAME, F+1→G, L+2→N, A+3→D, M+4→Q, E+5→J.

Hence, the answer is GNDQJ. - In a certain code “PIEGON” is written as “OHDFNM”. How is “OSTRICH” written in that code?

a) BWKXUAF

b) NRSQHBG

c) SHXALCE

d) GQWPNCV

Answer: b

Explanation: Here, each letter moves -1 from its original position.

i.e. for “PIEGON” the code is OHDFNM.

Similarly, for “OSTRICH” the code is NRSQHBG.

Hence, the answer is NRSQHBG. - Introducing a boy, a man said, “He is son of my father’s grandson”. How is that man related to the boy?

a) Father

b) Brother

c) Grandfather

d) Husband

Answer: c

Explanation: Here, it is given that the boy is son of man’s father’s grandson i.e. the boy is son of that man’s son. So, the boy is grandson of that man.

Hence, the answer is Grandfather. - If P is sister of T, V is brother of K and T is son of V.M is mother of P, L is son of K. How is V related to M?

a) Father

b) Grandson

c) Brother

d) Husband

Answer: d

Explanation: Here, it is clear that V is brother of K and T is son of V and P is sister of T. if M is mother of P then V definitely is husband of M.

Hence the answer is Husband. - K is the son of A’s father’s sister. D is the father of G and grandfather of A. P is the daughter of H who is grandmother of K. D is husband of H and G is husband of L. Who is mother of K?

a) A

b) L

c) P

d) H

Answer: c

Explanation: Here, it is given that A’s father is G and K is son of A’s father’s sister i.e. G’s sister. Since, P is sister of G therefore, P is the mother of K.

Hence the answer is P. - GTFC : MYLH :: KMFE : ?

a) PRLK

b) DZSX

c) DAEK

d) EGJR

Answer: a

Explanation: From analyzing the left side, we can conclude that each letter of the first group is moved 5 step forward to obtain the corresponding letter of the second group.

i.e. G + 5 ➔ M, T + 5 ➔ Y, F + 5 ➔ L, C + 5 ➔ H.

By using the same logic, we can conclude that PRLK is the correct answer. - Greece : Athens :: Kenya : ?

a) London

b) Nairobi

c) Amsterdam

d) Prague

Answer: b
