Correct Answer: 46
Explanation:
Let the number of students = 100
Number of students who failed in one or more subjects = 14 + 22 + 18 = 54%
The percentage of students who passed in both the subjects = 100 - 54 = 46%.
Correct Answer: 4 yrs
Explanation:
From the given data in the question,
t = 4 years.
Correct Answer: 60
Explanation:
Total engineers = 4800
Number of female engineers = 3/8 x 4800 = 1800
Then, number of male engineers = 4800 - 1800 = 3000
Now, required is female engineers is what percentage of the number of male engineers
=> 1800 is what % of 3000
=> p x 3000/100 = 1800
=> 30p = 1800
p = 60%
Hence, female engineers is 60 percentage of the number of male engineers.
Correct Answer: 1947
Explanation:
Given 82.5% of 2360
Correct Answer: 12.5%
Explanation:
Let p% of a day is 3 hrs.
We know that a day has 24 hrs.
=> p x 24/100 = 3
=> p = 300/24
=> p = 12.5%
Hence, 3 hrs is 12.5% of a day.
Correct Answer: 5/4
Explanation:
Literally any percentage means divide by 100.
So
. That can be reduced to 5/4.
To convert to a decimal, you can do long division, dividing 5 into 4.
Correct Answer: 1250
Explanation:
Let initially 'X' ticket has been sold.
So now in 2nd week 20% increases, so
=> X x 120/100
In 3rd week 16% increases, so
=> X x (120/100) x (116/100)
In 4th week 20% decrease, so
=> X x (120/100) x (116/100) x (80/100) = 1392
X = 1250.
Correct Answer: 432
Explanation:
There are 600 Kabaddi players
4% wear knee band on one leg
Remaining players = 600 x 0.96 = 576
Of the remaining, 25% wear knee bands on both leg
and Of the remaining, 75% do not wear knee bands .
So players not wearing knee bands = 0.75 x 576 = 576 x 3/4 = 144 x 3 = 432.
Correct Answer: 70% is better
Explanation:
Let Price be Rs.100
1st CASE:
Then 100 x 70/100 = 70
=> price after discount = 100-70 = Rs.30
2nd CASE:
Then 100 x 40/100 = 40
=> price after discount = 100-40 = Rs.60
then
60 x 30/100 = 18
=> price after 2 consequent discount = 60-18 = Rs.42
=>from 1 and 2 cases, 70% discount is better.
