If 25% of three-seventh of 26% of a number is 145.5, what is the number?

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%

Correct Answer: 0.765D

=>  12 100 - 12 x 100

 

= 1200/88

 

= 13.636%

Correct Answer: 64,000

Explanation:

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

Now, N = 5/4 x 32000 = 40000

Hence, karthik's monthly salary = Rs. 64000.

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

=>  $$\begin{gathered} p x 80 100 = 15 \\ ? p = 15 x 100 80 \\ ? p = 1500 80 = 18 . 75 \end{gathered}$$

 

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
