what is 70 of 50 means 70% of 50

$$\begin{gathered} ? 70 x 50 100 \\ = 7 x 5 \\ = 35 \end{gathered}$$

Hence, 70 of 50 is 35.

Given 

4 4 5 of 259.99 = ? % of 1247.9

24/5 x 260 = ? x 1248/100

? = 1248 x 100/1248

? = 100.

Given 82.5% of 2360

  82 . 5 100 x 2360 = 0 . 825 x 2360 = 1947

Total engineers = 4800

Number of female engineers = 3/8 x 4800 = 1800

Then, number of male engineers = 4800 - 1800 = 3000

Now, required is female engineers is what percentage of the number of male engineers

=> 1800 is what % of 3000

=> p x 3000/100 = 1800

=> 30p = 1800

p = 60%

Hence, female engineers is 60 percentage of the number of male engineers.

From the given data in the question,

$$\begin{gathered} 279841 = 160000 x 1 + 15 100 t \\ 279841 160000 = 115 100 t \end{gathered}$$

t = 4 years.

Let the number of students = 100

Number of students who failed in one or more subjects = 14 + 22 + 18 = 54%

The percentage of students who passed in both the subjects = 100 - 54 = 46%.

Ramesh : Rajesh =(50,000*36) : (75,000*30) =4 : 5.

Therefore, Rajesh's share=Rs.(27,000*5/9)= Rs.15,000.

Let the Original capital amount be Rs. P

Given after 2 years the amount is Rs. 10000

Rate of interest = 30%

According to the question,

$$\begin{gathered} P x 130 100 x 130 100 = 10000 \\ = > P = 1000000 169 = 5917 \end{gathered}$$

Therefore, the capital amount P = Rs. 5917

Let p% of a day is 3 hrs.

We know that a day has 24 hrs.

=> p x 24/100 = 3

=> p = 300/24

=> p = 12.5%

Hence, 3 hrs is 12.5% of a day.

Literally any percentage means divide by 100.

So 125 % = 125 100. That can be reduced to 5/4.

To convert to a decimal, you can do long division, dividing 5 into 4.
