From the given data,

20% of K = 32% of N

V = 4/5 N

 

Given Vipin's salary = 3.84 lpa = 3.84/12 = 32,000 per month

Correct Answer: 60%

Explanation:

              Men               Women

 

              600x               400x

 

      Total engineers = 480x

 

      Male engineers = 480x X 0.66 = 320

 

   Women who are Engineers  = 160x 

 

  Women are not Engineers  = 400x - 160x = 240x

 

 Required percentage = 240 400 x 100 = 60%

25% of three-seventh of 26% of a number is 145.5

 

Let the required number be 'N'

 

i.e,  25 100 x 3 7 x 26 100 x N = 145 . 5

 

N =  145 . 5 x 7 x 10000 75 x 26

 

=> N = 5223.07

Correct Answer: 18.75%

Explanation:

Given that to find 15 of 80

=> What % of 80 is 15

Let it be 'p'

=> p% of 80 = 15

Therefore, 15 is 18.75% of 80 => 18.75% of 80 = 15

 

Example::

Now, in the similar way we can find 15% of 80 =?

=> 15x80/100 = p

=> p = 4 x 3 = 12

 

Therefore, 15% of 80 = 12
