Kavya Saxena answered |
Option ( c) 341 is correct.
Explanation:-
{Let the initial radius of circle = 10 cm
Then, it's area = π r^ 2
= π (10) ^2
= 100 π cm square.
Given, (radius is increased by 110%)
New radius = ( 100+110) % of 10 cm
=> 210% of 10 cm
{ 210 /100 * 10} cm
=> 21 cm
Therefore, area of circle of radius (21) cm
=> π (21) ^2
=> 441 π cm square.
Increase in area= ( 441 π - 100 π ) cm square.
=> 341 cm square. }
=> 341 cm square. }

Pass marks is 650+50=700
which is 35 % of the total marks
let x be the max marks
then 35% of x = 700
x = 2000
which is 35 % of the total marks
let x be the max marks
then 35% of x = 700
x = 2000

Prakhya Shrivastava answered |
Let 100 be the wages of man if it decreases by 50%, his wages become
100-(50%of 100) = 100-50 =50
Now his wages is 50
when it is increases by 50% then angain his salery become
50+(50%of50) = 50+25 = 75
He has loss of 100-75 = 25
In % = (25×100)/100 = 25%
Thus he has loss of 25%. Hence option (d) is correct.

Kavya Sharma answered |
x increased by 37 1/2% ( of x) gives 33, or
x + (37 1/2 % * x) = 33
x + (37.5%x) = 33
1x + (.375x) = 33
1.375x = 33
Divide both sides by 1.375
x = 24

Notes Wala answered |
The correct option is C.
Vote secured by defeated candidate = 40%
vote secured by winner candidate= 100-40=60%
Difference of vote% = 60-40=20%
So, 20% = 300. 100% = 300×100/20 = 1500
Vote secured by defeated candidate = 40%
vote secured by winner candidate= 100-40=60%
Difference of vote% = 60-40=20%
So, 20% = 300. 100% = 300×100/20 = 1500

The correct option is C as
Let original price of a unit be Rs. 100
Increased price = Rs. 160
Reduction on Rs. 160 = Rs. 60
Reduction on Rs. 100 = 60/160 * 100 = 37.5 %
Let original price of a unit be Rs. 100
Increased price = Rs. 160
Reduction on Rs. 160 = Rs. 60
Reduction on Rs. 100 = 60/160 * 100 = 37.5 %

Crafty Classes answered |
Given:
- Rajesh is 40% older than Neeraj.
We need to find out how much percentage younger Neeraj is compared to Rajesh.
Step 1: Let Neeraj's age be N.
- Since Rajesh is 40% older, Rajesh's age will be:
Rajesh’s age = N + 40% of N = N + 0.4N = 1.4N
Step 2: Find the percentage by which Neeraj is younger than Rajesh.
- The difference in age between Rajesh and Neeraj is:
Difference in age = 1.4N − N = 0.4N - Now, to find how much younger Neeraj is as a percentage of Rajesh's age, we use the formula:
Substituting the values:
Neeraj is 28.57% younger than Rajesh, which matches the fraction
Thus, the correct answer is Option A:
Neeraj is 28.57% younger than Rajesh, which matches the fraction
Thus, the correct answer is Option A:

Given:
- A student who gets 36% of marks, fails by 32 marks.
- Another candidate who gets 45% marks gets 40 marks more than are necessary for passing.
To find:
- Maximum marks
Solution:
Let the maximum marks be x.
From the given data,
- The first student gets 36% marks and fails by 32 marks. So,
- Marks obtained by the first student = 36% of x
- Marks required to pass = (100% - 36%) of x = 64% of x
- According to the question, the first student fails by 32 marks. So,
- 36% of x - 64% of x = 32
- -28% of x = 32
- x = 32/(-28%) = 114.28 ≈ 114 (rounded off to the nearest integer)
- The second student gets 45% marks and gets 40 marks more than are necessary for passing. So,
- Marks obtained by the second student = 45% of x
- Marks required to pass = (100% - 45%) of x = 55% of x
- According to the question, the second student gets 40 marks more than are necessary for passing. So,
- 45% of x - 55% of x = 40
- -10% of x = 40
- x = 40/(-10%) = 400
Therefore, the maximum marks are 400.
Hence, option B is the correct answer.
- A student who gets 36% of marks, fails by 32 marks.
- Another candidate who gets 45% marks gets 40 marks more than are necessary for passing.
To find:
- Maximum marks
Solution:
Let the maximum marks be x.
From the given data,
- The first student gets 36% marks and fails by 32 marks. So,
- Marks obtained by the first student = 36% of x
- Marks required to pass = (100% - 36%) of x = 64% of x
- According to the question, the first student fails by 32 marks. So,
- 36% of x - 64% of x = 32
- -28% of x = 32
- x = 32/(-28%) = 114.28 ≈ 114 (rounded off to the nearest integer)
- The second student gets 45% marks and gets 40 marks more than are necessary for passing. So,
- Marks obtained by the second student = 45% of x
- Marks required to pass = (100% - 45%) of x = 55% of x
- According to the question, the second student gets 40 marks more than are necessary for passing. So,
- 45% of x - 55% of x = 40
- -10% of x = 40
- x = 40/(-10%) = 400
Therefore, the maximum marks are 400.
Hence, option B is the correct answer.

Let the original price of rice = Rs. x/kg
New price = Rs 4x/5 kg
According to question,
[1600/(4x/5)] - (1600/x) = 10
=>(8000/4x) - (1600/x) = 10
=>40x = 1600 {By solving above equation}
=>x = 40
Hence the original price of rice is 40 rupees per kg.
for the reduced price equal to=(4/5)×40
=32
therefore the new price of rice is 32 rupees per kg
HENCE OPTION C IS THE ANSWER
New price = Rs 4x/5 kg
According to question,
[1600/(4x/5)] - (1600/x) = 10
=>(8000/4x) - (1600/x) = 10
=>40x = 1600 {By solving above equation}
=>x = 40
Hence the original price of rice is 40 rupees per kg.
for the reduced price equal to=(4/5)×40
=32
therefore the new price of rice is 32 rupees per kg

36% of x = 113 + 85
= 198
x = 198 * 100/36
= 550
Max marks= 550

Problem Solving Strategy:
Let the maximum marks be x.
According to the given question,
35% of x = 650 + 50
= 700
Hence, we can find x by using the formula:
35/100 * x = 700
x = 2000
Solution:
Therefore, the maximum marks are 2000. Hence, the correct answer is option (c).

∵ (62% of N - 38% of N) =144
⇒ 24% of N = 144
∴ N = (144 x 100)/24 = 600

Solution:
Given,
Percentage of students failed in Hindi = 42%
Percentage of students failed in English = 52%
Percentage of students failed in both the subjects = 17%
Let's assume the total number of students appeared for the examination be 100.
Number of students failed in Hindi = 42% of 100 = 42
Number of students failed in English = 52% of 100 = 52
Number of students failed in both subjects = 17% of 100 = 17
Now, we need to find the percentage of students who passed in both subjects.
Number of students who failed in at least one subject = Number of students failed in Hindi + Number of students failed in English - Number of students failed in both subjects
= 42 + 52 - 17 = 77
Number of students who passed in both subjects = Total number of students - Number of students who failed in at least one subject
= 100 - 77 = 23
Percentage of students who passed in both subjects = (Number of students who passed in both subjects / Total number of students) * 100%
= (23/100) * 100%
= 23%
Therefore, the percentage of students who passed in both subjects is 23%, which is option A.
Given,
Percentage of students failed in Hindi = 42%
Percentage of students failed in English = 52%
Percentage of students failed in both the subjects = 17%
Let's assume the total number of students appeared for the examination be 100.
Number of students failed in Hindi = 42% of 100 = 42
Number of students failed in English = 52% of 100 = 52
Number of students failed in both subjects = 17% of 100 = 17
Now, we need to find the percentage of students who passed in both subjects.
Number of students who failed in at least one subject = Number of students failed in Hindi + Number of students failed in English - Number of students failed in both subjects
= 42 + 52 - 17 = 77
Number of students who passed in both subjects = Total number of students - Number of students who failed in at least one subject
= 100 - 77 = 23
Percentage of students who passed in both subjects = (Number of students who passed in both subjects / Total number of students) * 100%
= (23/100) * 100%
= 23%
Therefore, the percentage of students who passed in both subjects is 23%, which is option A.
