Correct Answer: 0.0625
Explanation:
25% of 25% means
25/100 of 25/100
i.e, 1/4 of 1/4
or in other words 1/4 x 1/4=1/16
Hence, the answer is 1/16 = 0.0625.
Correct Answer: 700
Explanation:
Let number of boys in the school = x
Let number of girls in the school = y
Number of students participated in the sports = 300
Out of which boys = 100
but given number of boys participated in sports = x/3
=> x/3 = 100
=> x = 300
Remaining girls = 300 - 100 = 200
=> y/2 = 200
=> y = 400
Therefore, total number of students in the school = x + y = 300 + 400 = 700
Correct Answer: 96.1%
Explanation:
Non- defective products
Correct Answer: Rs. 168 less
Explanation:
Cost of each cake P1 & P2 = Rs. 12
Offer decrease in % = 20%
Increase in sale per day (Q2) = 250 - 18%
Total quantity per day (Q1) = 250
Hence, required change total revenue
TR = P2Q2 - P1Q1 = (12 x 0.8 x 250 x 1.18) - (12 x 250) = - Rs.168.
Correct Answer: 100 & 4
Explanation:
Let the first number be x and the second number be y.
Given
5% of x = (25% of y) + y
=> 5x/100 = 5y/4
=> x = 25y ......(1)
and also given that, x - y = 96
=> x = 96 + y .....(2)
From (1)&(2)
25y = 96 + y
=> 24y = 96
=> y = 4
From (1)
x = 96 + 4 = 100
Hence, the numbers are 100 & 4.
Correct Answer: 20
Explanation:
Let the rquired number be 'P'
According to the question,
Hence, 100 percent of the number 20 is 20.
Now, you can also try for

Hence, 20 percent of the number 500 is 100.

Thus, 8/35 of the land will cost = 30,000 x 28 x 4/15
= Rs. 2,24,000.
Correct Answer: 140
Explanation:
x - 35 = 80x/100
=> x = 175
=> 4x/5 = 4x175/5 = 140.
Correct Answer: None of these
Explanation:
Physics Chemistry
Failed 35% 45%
Passed 65% 55%
Passed in both = 22% of total student
percentage of students who are passed in any of the physics or chemistry or both =(65+55) - 22 = 98%
So, the percentage of students who are failed in both = 2%
Therefore, total failed (in both subjects) students = 12
