Correct Answer: 543
Explanation:
Number of employees leaving job
= 25% of 724 = (1/4) x 724 = 181
? Number of rest of the employees
= 724 - 181 = 543
Correct Answer: 162/3
Explanation:
Required decrease in consumption = [a/(100 + a)] x 100%
= [20/(100 + 20)] x 100%
= (20/120) x 100%
= 162/3%
Correct Answer: 33.1%
Explanation:
Total rate of increase in population per annum = 10%
Initially, let the population be 1000
population after 3 yr = 1000(1 + 10/100)3
= (1000 x 11/10 x 11/10 x 11/10) = 1331
? Increase in percentage = [(1331 - 1000)/1000] x 100%
= (331/1000) x 100%
= 33.1%
Correct Answer: 10%
Explanation:
Here, Z = 100, X = 80 and Y = 72
Now according to the formula,
Percentage change = (New amount - Original amount)/Original amount
= [(80 - 72)/80] x 100%
= (8/80) x 100%
= 10%
? Y is less by X = 10%
Correct Answer: 500
Explanation:
Let x% candidates take both the subjects.
Percentage of candidates who opted Physics = 65.8%
and percentage of candidates who opted Mathematics = 59.2%
? x = (65.8 + 59.2 - 100)% = (125 - 100)% = 25%
Also, total number of candidates = 2000
? Number of candidates who opted both the subjects
= 25 x 2000/100 = 500
Correct Answer: ? 13800
Explanation:
Given that, P = ? 15000, and Q = 8
According to the formula,
Required new price = [(100 - Q)/100] x P
= [(100 - 8)/100] x 15000
= (92/100) x 15000
= ? 13800
Correct Answer: ? 800
Explanation:
Let a man have = ? N.
Remainder money, after losses 20% of his money
= N - 20% of N
= N - (N x 20)/100
= (5N - N)/5
= 4N/5
Remainder money, after spending 25% of his remainder money
= 4N/5 - 25% of (4N/5)
= 4N/5 - (4N/5) x (25/100)
= 4N/5 - N/5
= (4N - N)/5
= 3N/5
According to the question,
3N/5 = 480
? x = 480 x 5/3 = ? 800
Correct Answer: 35
Explanation:
Ans = 12 x (26/100) x (5/78) x (38/100) x (7/152) x 10000
= 12 x (5/3) x (7/4)
= 35
Correct Answer: 662/3 %
Explanation:
Let kamal's marks be 100
? Shantanu's marks = 60
Kamal has 40 marks more than Shantanu
? Required percentage = (40/60) x 100%
= 662/3 %
Correct Answer:
Explanation:
Net effect = [- 12 - 4 + {(-12) (-4)/100}]%
= (-16 + 0.48)%
= -15.52%
