QUESTION: 1

### The flow of water through a pipe of radius 28cm into a rectangular tank which is 400m long and 176 m wide is 20 km/hr. In what time the water level will rise by 56 cm.

Solution:

Let time taken to increase the level of tank by 56 m =‘t’ hours.

The volume of pipe contains the water, has speed of water = Height of pipe.

Volume of Pipe = 22/7 × (28/100)² × 20,000

Volume of pipe × n = 400 × 176 × 56/100 22/7 × (28/100)² × 20,000 × t

= 400 × 176 × 56/100

Therefore, t = 8 hours

QUESTION: 2

### A swimming pool has two pipes one can fill it with water in 32 hours and other can empty it in 12 hours. In how many hours will the swimming pool be emptied if both the pipes are opened together when 3/8th of the swimming pool is already filled with water?

Solution: If both pipes are open, then total units per hour empty the swimming pool (P - Q) = 3 - 8 = - 5 units

According to question,

Swimming pool has 3/8th of its total capacity in the beginning 3/8 × 96 = 36 units

Time taken to empty the swimming pool = 36/ (-5) = 7 (1/5) hour

QUESTION: 3

### Find the wrong number in the given number series: 20 9 10 17 29 71.5

Solution: QUESTION: 4

If the speed of a boat in still water is 60 km/h. If the boat travels 180 km along the stream in 2 hours 30 minutes, then the time taken by it to cover the same distance against the stream will be?

Solution:

Let the speed of the current be ‘x’ km/h

Rate Downstream = (x + 60) km/h

According to the question,

180/(x + 60) = 2 hours 30 minutes 180/(x + 60) = 5/2 hours

(x + 60) = 72

Therefore, x = 12 km/hr Rate

Upstream = 60 – 12 = 48 km/hr

Required time = 180/48 = 3 hours 45 minutes

QUESTION: 5

How many words can be formed the word AMAZON in which both A’s do not come together?

Solution:

Total number of letters in the word AMAZON is 6.

Total number of ways = 6!/2!

Number of ways when 2 A’s are together = (5! × 2!)/ 2! = 120

Therefore, Number of ways when 2 A’s are not together = 360 – 120 = 240

QUESTION: 6

If 35% of 40% of 7/5 of a number is 980, then what is 25% of 3/2of that number?

Solution:

Let the number be ‘a’

35/100 × 40/100 × 7/5 × a = 980

a = 5000

Therefore, required answer = 25% of 3/2 of 5000 = 1875

QUESTION: 7

Directions -
In the following question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.

Q. What is the speed of a motorboat in still water?

I. The motorboat covers a distance of 140 km in 4 hours while running upstream.
II. It covers the same distance in 3 hours 30 minutes while running downstream.

Solution:

From I and II

Let the speed of the motorboat be a km/hr

Speed of the stream be b km/hr

Speed of upstream a - b= 140/4 = 35 ……(i)

Speed downstream a + b = 140/ 3(1/2) = 40 …….(ii)

Solving (i) and (ii),

we get a= 37.5 km/hr and b = 2.5 km/hr

QUESTION: 8

The number 711711711711711711711 is Divisible by

Solution:

Clearly, we can see that it is not divisible by 7 and

(Sum of digits at odd places) – (sum of digits at even places) = 35 – 28 = 7

Therefore, Given number is not divisible by 11.

QUESTION: 9

The flagstaff of 9 meters high, is placed on the top of a tower makes a shadow of 3√3 m eters along the ground, then find the angle that the sun makes with the ground.

Solution: Let a = height of the tower & b = length of the shadow of the tower

Then, tan (x) = a/b

= (9 + a)/3√3 + b

= 3√3a = 9b

= a/b = 9/3√3

Therefore, a/b = √3 Tan (x) = tan 60°

so x = 60

QUESTION: 10

The average age of a husband and wife, who were married 8 years ago, was 30 years at the time of their marriage, Now, the average age of the family, including husband, wife and a child, born during the interval, is 26 years. What is the present age of the child?

Solution:

Total age 8 years ago = 30 × 2 = 60 years

Total age today = 60 + 8 × 2 = 76 years

Total age after child was born = 76 + a

Therefore, average age = (76 + a)/3 = 26 Now, 76 + a = 78

Therefore, a = 2 years

QUESTION: 11

If a = (√3 + 1) and b = (1 - √3), then find the value of (a² + b² + ab).

Solution:

(a² + b² + ab) = a² + b² + 2ab – ab

= (a + b)² - ab

= (√3 + 1 + 1 - √3)² – (√3 + 1)(1 - √3)

= 2² - (- 3 + 1)

= 4 + 2

= 6

QUESTION: 12

A conical vessel, whose internal radius is 7cm and height is 24cm, is full of milk. If the milk is poured into a cylindrical vessel with internal radius 14cm, find the height to which the milk rises in it.

Solution:

Let the height up to which milk rises in cylindrical vessel = h cm

Then, Volume of cylinder = 22/7 × r² × h

Volume of cone = 1/3 × 22/7 × r² × h

Now,

22/7 × 14² × h = 1/3 × 22/7 × 7² × 24

Therefore, h = 2 cm

Solution:   QUESTION: 15

An amount of Rs 34,000 is to be divided among Raja, Rani and Mahi in the ratio of 1/4: 5/16:1/2. Find the difference between the smallest and the greatest parts.

Solution:

Raja: Rani: Mahi = 1/4: 5/16:1/2

Ratio = 4:5:8

Difference between greatest and smallest = 8x – 4x = 4x

Now, 4x + 5x + 8x = 34000

17x = 34000

Therefore, x = 2000

Required answer = 4x = 4 × 2000 = 8000

QUESTION: 16

Praiksha and Mohit enters into a partnership investing Rs 8000 and Rs 12000 respectively. After 3 months, Pariksha withdrew Rs 2500, while Mohit invested Rs 2500 more. After 3 months more, Suvarna joins the business with a investment of Rs 10,500. After a year, they obtained a gain of Rs 30300. By what money does the share of Mohit exceeds the share of Suvarna?

Solution:

Pariksha investment = 8000 × 3 + 5500 × 9 = 24000 + 49500 = 73500

Mohit investment = 12000 × 3 + 14500 × 9 = 36000 + 130500 = 166500

Suvarna investment = 10500 × 6 = 63000

Ratio’s of their investment = 49:111:42

Difference between Mohit and Suvarna = 111 – 42 = 69

Therefore, 69/202 × 30300 =Rs 10350

QUESTION: 17

In an election two candidates participated. 15% voters did not vote. 20% declared invalid and the winner got 75% of the valid votes. If he won by 3400 votes, find the number of voters in the voting list.

Solution:

Total numbers of voters be 100.

Numbers of voters who voted (85%) = 85

Number of valid votes = 85 × 80/100 = 68

Winning candidate got 75% of valid votes = 75/100 × 68 = 51

Looser got = 68 – 51 = 17

Difference between winning and losing candidates votes = 3400

51 – 17 = 3400

34 = 3400

100 = 3400/34 × 100 = 10,000

QUESTION: 18

The perimeter of a rectangle is 300m. If the difference between the length and breadth of the rectangle is 10m, then what is the circumference of the largest circle that can be drawn inside the rectangle?

Solution:

Perimeter = 2(l + b)

2(l + b) = 300 (l + b) = 150m

Now, b + 10 + b = 150

2b = 140

b = 70m

The largest circle drawn inside the rectangle will have diameter equal to the breadth of the rectangle.

Circumference of the circle = 22/7 × d

= 22/7 × 70

= 220 m

QUESTION: 19

A solution contains 40L of pure milk. 25% of his this is taken out. Another 25% of the remaining solution is taken out and finally 25% of the contents left is taken out. The total content taken out replaced with water. Find the ratio of milk to water in the final solution.

Solution:

Quantity of milk = 40L

When 25% solution is taken out =25/100 × 40 = 10 L

Remaining solution = 40 L – 10 L = 30 L

Now, again 25% of solution is taken out = 25/100 × 100 = 7.5 L

Remaining solution = 30 L – 7.5 L = 22.5 L

Now, further 25% of solution is taken out = 25/100 × 22.5 = 5.625 L

Remaining solution = 22.5 L – 5.625 L = 16.875 L

Total quantity taken out which is replaced by water = 40 L – 16.875 L = 23.125 L

Therefore, Required ratio = 23.125 : 16.875 = 37:27

QUESTION: 20
