## OSSSC RI, ARI, AMIN, SFS, ICDS Supervisor 2024 Practice Test-3

- A 25 cm wide path is to be made around a circular garden having a diameter of 4 meters. Approximate area of the path in square meters is:

(a) 3.34

(b) 2

(c) 4.5

(d) 5.5

Answer: (a) 3.34

Solution:

Radius of the inner circle = 4/2 = 2 meters

Radius of the outer circle = 2 + 0.25 = 2.25 meters

Area of the path = π(2.25² – 2²) = π(5.0625 – 4) = π(1.0625) = 3.34 sq meters - A cuboidal block of 6 cm X 9 cm X 12 cm is cut up into an exact number of equal cubes. The least possible number of cubes will be:

(a) 6

(b) 9

(c) 24

(d) 30

Answer: (c) 24

Solution:

Volume of the block = 6 * 9 * 12 = 648 cm³

Side of the largest cube = H.(c)F. of 6, 9, and 12 = 3 cm

Volume of one cube = 3³ = 27 cm³

Number of cubes = 648 / 27 = 24 - I. 9a2 + 18a + 5 = 0,

II. 2b2 + 13b + 20 = 0 to solve both the equations to find the values of a and b?

(a) If a > b

(b) If a ≥ b

(c) If a < b

(d) If a ≤ b

Ans: (a) If a > b

Explanation:

I. 9a2 + 3a + 15a + 5 = 0

=>(3a + 5)(3a + 1) = 0 => a = -5/3, -1/3

II. 2b2 + 8b + 5b + 20 = 0

=>(2b + 5)(b + 4) = 0 => b = -5/2, -4

a is always more than b.

a > b. - 9000 + 16 2/3 % of ? = 10500

(a) 1500

(b) 1750

(c) 9000

(d) 7500

Ans: (c) 9000

Explanation:

9000 + 16 2/3 % of ? = 10500 => 9000 + 50/3 % of ? = 10500

50/(3 * 100) of ? = 1500 => ? = 1500 * 6

? = 9000 - Two pipes A and B can fill a cistern in 37 1/2 minutes and 45 minutes respectively. Both pipes are opened. The cistern will be filled in just half an hour, if the pipe B is turned off after?

(a) 5 min

(b) 9 min

(c) 10 min

(d) 15 min

Ans: (b) 9 min

Explanation:

Let B be turned off after x minutes. Then, part filled by (A + (b) in x min + part filled by A in (30 – x) min = 1.

x(2/75 + 1/45) + (30- x) 2/75 = 1

11x + 180 – 6x = 225 => x = 9 - Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is?

(a) 60 gallons

(b) 100 gallons

(c) 120 gallons

(d) 180 gallons

Ans: (c) 120 gallons

Explanation:

Work done by the waste pipe in 1 minute = 1/15 – (1/20 + 1/24) = – 1/40

Volume of 1/40 part = 3 gallons\

Volume of whole = 3 * 40 = 120 gallons. - 11th term of the (a)P. -3, -1/2, 2 …. is

(a) 28

(b) 22

(c) -38

(d) -48

Ans. (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 - ∠B = ∠E, ∠F = ∠C and AB = 3 DE in triangles ABC and DEF. The two triangles are

(a) congruent but not similar

(b) similar but not congruent

(c) neither similar nor congruent

(d) similar as well as congruent

Ans. (b) similar but not congruent

Explanation: In ΔABC and ΔDEF,

∠B = ∠E, ∠F = ∠C and AB = 3 DE

By AA similarity criterion,

ΔABC ~ ΔDEF

AB = 3DE

⇒ AB/DE = 3

⇒ AB/DE = BC/EF = AC/DF = 3

Triangles must have a side ratio of 1 to be congruent.

Therefore, triangles are similar but not congruent. - The bucket’s two-round ends have sizes of 44 cm and 24 cm. The bucket stands 35 centimetres tall. The bucket has a capacity of

(a) 32.7 litres

(b) 33.7 litres

(c) 34.7 litres

(d) 31.7 litres

Ans. (a) 32.7 litres

Explanation: Given,

The bucket’s height is h = 35 cm.

One bucket’s circular end has a diameter of 44 cm.

The radius R = 22 cm is then calculated.

Another end’s diameter is 24 cm.

The radius r = 12 cm is then calculated.

We know that Volume of the bucket = (1/3)πhR2 + r2 + Rr

= (1/3) × (22/7) × 35 × (22)2 + (12)2 + 22 × 12

= (35/3) × (22/7) × (484 + 144 + 264)

= (5 × 22 × 892)/3

= 32706.6 cm3

= 32.7 litres. - The probability of a non-leap year with 53 Sundays being chosen at random is

(a) 1/7

(b) 2/7

(c) 3/7

(d) 5/7

Ans. (a) 1/7

Explanation: Non-leap year = 365 days

52 weeks Plus 1 day Equals 365 days

The number of Sundays in a 52-week period equals 52.

Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday are all possible options for the last day.

The total number of possible outcomes: 7.

1 is the number of positive results.

As a result, the chance of receiving 53 Sundays is 1/7 - What is the next number in the series: 2, 4, 8, 16, ___?

(a) CMN

(b) UJI

(c) VIJ

(d) IJT

Answer: (c) VIJ

Explanation: Each letter in the series is moved one step forward in the English alphabet, so the next letters are VIJ. - B2CD, _____, BCD4, B5CD, BC6D

(a) B2C2D

(b) BC3D

(c) B2C3D

(d) BCD7

Answer: (c) B2C3D

Explanation: Each term consists of the letter “B”, followed by a number, then “CD”. The numbers increase sequentially by 1, so the missing term is B2C3(d) - If it is currently 3:45 PM, what will be the angle between the hour hand and the minute hand of the clock?(a) 90 degrees

(b) 187.5 degrees.

(c) 120 degrees

(d) 135 degreesAnswer: (b) 187.5 degrees.

Explanation:

To find the angle between the hour hand and the minute hand at 3:45 PM:The hour hand will be slightly past 3 but not yet at 4, so it will be closer to 3.

The minute hand will be at 9 (since 45 minutes is three-quarters of an hour).

The angle formed between the hour hand and the 12 o’clock position is (3 * 30) + (45/2) = 97.5 degrees.

The angle formed between the minute hand and the 12 o’clock position is 45 * 6 = 270 degrees.

The difference between these two angles gives the angle between the hour hand and the minute hand: 270 – 97.5 = 172.5 degrees.

However, since we want the smaller angle between them, we subtract this from 360 degrees: 360 – 172.5 = 187.5 degrees. - Arrange the following words in a logical and meaningful order:

Explanation:

- World is the largest geographical entity.
- India is a country within the world.
- Maharashtra is a state in India.
- Mumbai is a city in Maharashtra.
- Gateway of India is a monument in Mumbai.

The correct logical order is World → India → Maharashtra → Mumbai → Gateway of India.
