Kiran Reddy answered |
Total number of votes = 7500
Given that 20% of Percentage votes were invalid
⇒ Valid votes = 80%
Total valid votes = 7500*(80/100)
1st candidate got 55% of the total valid votes.
Hence the 2nd candidate should have got 45% of the total valid votes
⇒ Valid votes that 2nd candidate got = total valid votes x (45/100)
7500*(80/100)*(45/100) = 2700
Given that 20% of Percentage votes were invalid
⇒ Valid votes = 80%
Total valid votes = 7500*(80/100)
1st candidate got 55% of the total valid votes.
Hence the 2nd candidate should have got 45% of the total valid votes
⇒ Valid votes that 2nd candidate got = total valid votes x (45/100)
7500*(80/100)*(45/100) = 2700

Prepworks Coaching answered |
Clearly, the playground is of rectangular shape.
So the required length of the wire
= Perimeter of the rectangle
= 2 (length + breadth)
= 2 (250+20) = 540 m.
So the required length of the wire
= Perimeter of the rectangle
= 2 (length + breadth)
= 2 (250+20) = 540 m.

Mansi mehta answered |
Explanation:
Right Angled Triangle:
- In a right-angled triangle, one angle is a right angle, which is equal to 90 degrees.
- The other two angles are acute angles, which are less than 90 degrees.
- The sum of the two acute angles in a right-angled triangle is always equal to 90 degrees.
Given condition:
- One angle of the triangle is equal to the sum of the other two angles.
- Let the angles be x, y, and z, where x is the angle that is equal to the sum of y and z.
- Therefore, x = y + z.
- According to the given condition, x = y + z.
Conclusion:
- Since the given condition x = y + z is satisfied in a right-angled triangle, the triangle must be a right-angled triangle.
- Therefore, the correct answer is option 'B' - Right Angled Triangle.

Kiran Reddy answered |
Distance covered in 1st second = 5 cm
Distance covered in 2nd second = - 2 cm
∴ Total distance covered in two seconds
= 5 - 2 = 3 cm
Time taken in climb distance of 3 cm = 2 secs
Distance climbed by insect in 38 secs.
= 38/2 x 3 = 57cm
Distance covered in 39th secs
= 57 + 5
= 62 cm
Which is more than the rod height.
Hence, insect will climb the rod in 39 sec.
Distance covered in 2nd second = - 2 cm
∴ Total distance covered in two seconds
= 5 - 2 = 3 cm
Time taken in climb distance of 3 cm = 2 secs
Distance climbed by insect in 38 secs.
= 38/2 x 3 = 57cm
Distance covered in 39th secs
= 57 + 5
= 62 cm
Which is more than the rod height.
Hence, insect will climb the rod in 39 sec.

The given expression involves subtracting consecutive numbers in a pattern. Let's break down the expression step by step to find its value.
Step 1: 0 - 1 = -1
Step 2: -1 + 2 - 3 = -2
Step 3: -2 + 4 - 5 = -3
Step 4: -3 + 6 - 7 = -4
Step 5: -4 + 8 - 9 = -5
Step 6: -5 + 10 - 11 = -6
Step 7: -6 + 12 - 13 = -7
Step 8: -7 + 14 - 15 = -8
Step 9: -8 + 16 - 17 = -9

Given:
- (3/4)th of the balls are red
- (1/6)th are white
- Rest are blue
- 3 blue balls in the box
To find:
- Number of red balls
Solution:
Let the total number of balls in the box be 'x'.
- (3/4)x = number of red balls
- (1/6)x = number of white balls
- 3 = number of blue balls
We can find the total number of balls as follows:
x = (3/4)x + (1/6)x + 3
x - (3/4)x - (1/6)x = 3
(7/12)x = 3
x = (3*12)/7 = 36/7 (approx. 5.14)
Since the number of balls can only be a whole number, we can assume that there are 5 balls in the box.
- (3/4)*5 = 15/4 (approx. 3.75)
- (1/6)*5 = 5/6 (approx. 0.83)
- 5 - 3 = 2
Thus, there are 15/4 (approx. 3.75) red balls in the box.

- (1/6)x = number of white balls
- 3 = number of blue balls
We can find the total number of balls as follows:

x - (3/4)x - (1/6)x = 3
(7/12)x = 3
x = (3*12)/7 = 36/7 (approx. 5.14)
Since the number of balls can only be a whole number, we can assume that there are 5 balls in the box.

Urvashi choudhary answered |
Given information:
- Total number of students in the class = 60
- Girls are twice the number of boys
- Kamal is ranked 17th from the top
- There are 9 girls ahead of Kamal
Finding the number of boys and girls in the class:
Let the number of boys be x. Since girls are twice the number of boys, the number of girls would be 2x.
Total number of students in the class = Number of boys + Number of girls
60 = x + 2x
60 = 3x
x = 20
Therefore, there are 20 boys and 40 girls in the class.
Finding the number of students ahead of Kamal:
Since Kamal is ranked 17th from the top and there are 9 girls ahead of him, the number of students (including Kamal) ahead of him would be 17 + 9 = 26.
Finding the number of boys after Kamal:
The number of boys after Kamal would be the total number of boys minus the number of boys ahead of Kamal.
Number of boys after Kamal = Number of boys - Number of boys ahead of Kamal
= 20 - 26
= -6
Since the number of boys after Kamal cannot be negative, it means that there are no boys after Kamal in rank. Therefore, the answer is option C) 12.
- Total number of students in the class = 60
- Girls are twice the number of boys
- Kamal is ranked 17th from the top
- There are 9 girls ahead of Kamal
Finding the number of boys and girls in the class:
Let the number of boys be x. Since girls are twice the number of boys, the number of girls would be 2x.
Total number of students in the class = Number of boys + Number of girls
60 = x + 2x
60 = 3x
x = 20
Therefore, there are 20 boys and 40 girls in the class.
Finding the number of students ahead of Kamal:
Since Kamal is ranked 17th from the top and there are 9 girls ahead of him, the number of students (including Kamal) ahead of him would be 17 + 9 = 26.
Finding the number of boys after Kamal:
The number of boys after Kamal would be the total number of boys minus the number of boys ahead of Kamal.
Number of boys after Kamal = Number of boys - Number of boys ahead of Kamal
= 20 - 26
= -6
Since the number of boys after Kamal cannot be negative, it means that there are no boys after Kamal in rank. Therefore, the answer is option C) 12.

's age.
Let the age of the father be 5x and the age of the son be 2x (according to the given ratio).
Their product of ages is 1000, so we have:
5x * 2x = 1000
10x^2 = 1000
x^2 = 100
x = 10
Therefore, the age of the father is 5x = 50 years old.

Madhavi sharma answered |
To determine the code for the word HABIT, we need to analyze the given codes for the words HAT and RABBIT.
Given:
HAT is coded as 782
RABBIT is coded as 681192
Let's break down the codes and observe the pattern:
1. Code for HAT (782):
- The word HAT has three letters.
- The code consists of three digits.
- The first digit (7) represents the first letter 'H'.
- The second digit (8) represents the second letter 'A'.
- The third digit (2) represents the third letter 'T'.
2. Code for RABBIT (681192):
- The word RABBIT has six letters.
- The code consists of six digits.
- The first digit (6) represents the first letter 'R'.
- The second digit (8) represents the second letter 'A'.
- The third digit (1) represents the third letter 'B'.
- The fourth digit (1) represents the fourth letter 'B'.
- The fifth digit (9) represents the fifth letter 'I'.
- The sixth digit (2) represents the sixth letter 'T'.
From the given examples, we can observe that the code for each letter is determined by its position in the word. Therefore, the code for the word HABIT can be determined as follows:
- The word HABIT has five letters.
- The code should consist of five digits.
- The first digit should represent the first letter 'H'.
- The second digit should represent the second letter 'A'.
- The third digit should represent the third letter 'B'.
- The fourth digit should represent the fourth letter 'I'.
- The fifth digit should represent the fifth letter 'T'.
Based on this pattern, we can conclude that the code for HABIT is 78192. Therefore, the correct answer is option B: 78192.

Kiran Reddy answered |
Sales in year 2008 = 50
Sales in year 2009 = 30
Difference = 50 - 30 = 20
∴ Percentage decrease = 20/50 x 100 = 40%
Sales in year 2009 = 30
Difference = 50 - 30 = 20
∴ Percentage decrease = 20/50 x 100 = 40%
