There are two numbers. If 40% of the first number is added to the second number, then the second number increases to its five-fourth. Find the ratio of the first number to the second number?

There are two numbers. If 40% of the first number is added to the second number, then the second number increases to its five-fourth. Find the ratio of the first number to the second number?

A. 8 : 25
B. 25 : 8
C. 8 : 5
D. 5 : 8
E. None of these
Explanation:
Let the two numbers be x and y.
40/100 * x + y = 5/4y
=> 2/5 x = 1/4 y => x/y = 5/8

20% of 40 + ? % of 80 = 120

20% of 40 + ? % of 80 = 120

A. 140
B. 120
C. 160
D. 180
Explanation:
20% of 40 + ? % of 80 = 120
=> 800/100 + ?/100 * 80 = 120
=> ? = 140

In a company, 60% of the employees are men, of this 40 % are drawing more than Rs. 50000 per year. 36% of the total employees of the company draw more than Rs.50000 per year then what is the percentage of women who are drawing less than Rs. 5000 per year?

In a company, 60% of the employees are men, of this 40 % are drawing more than Rs. 50000 per year. 36% of the total employees of the company draw more than Rs.50000 per year then what is the percentage of women who are drawing less than Rs. 5000 per year?

A. 70%
B. 60%
C. 40%
D. 30%
Explanation:
Total number of employees be 100
Then number of men = 6000/100 = 60
Number of women = 4000/100 = 40
Therefore, number of men drawing more than Rs. 50000 = 2400/100 = 24 men
Since the number of total employees drawing more than Rs. 50000 = 3600/100 = 36
Number of women who draw more than Rs. 50000 = 36- 24 = 12
Number of women who draw less than Rs. 50000 = 40 -12 = 28
Therefore, Percentage of the women who draw less than Rs. 50000 per year = 28/40 x 100% = 70%
