Directions to Solve
The following pie-charts show the distribution of students of graduate and post-graduate levels in seven different institutes in a town.
Distribution of students at graduate and post-graduate levels in seven institutes:
2.
What is the ratio between the number of students studying at post-graduate and graduate levels respectively from institute S?
Answer: Option
Explanation:
| Required ratio = | (21% of 24700) | = | (21 x 24700) | = | 19 | . |
| (14% of 27300) | 14 x 27300 | 14 |

Divide 5187 and 3822 by 3 you will get 1729 and 1274. Then add units of each number i.e.,1+7+2+9 = 19 and 1+2+7+4 = 14.
Thus Ratio between PG and Grad of Institute S is 19:14.
@Gopal.
From where does this 3 comes from?

@ GOPAL, SARIKA & MANISHA.
P.G from Institute S = 24700*(21/100) = 247*21 = 5187.
Grad. from institute S = 27300*(14/100) = 273*14 = 3822.
P.G./Graduate = 5187/3822 {DIVIDE 5187 & 3822 BY 3} = 1729/1274 {DIVIDE 1729 &1274 BY 91} = 19/14.
P.G from Institute S = 24700*(21/100) = 247*21 = 5187.
Grad. from institute S = 27300*(14/100) = 273*14 = 3822.
P.G./Graduate = 5187/3822 {DIVIDE 5187 & 3822 BY 3} = 1729/1274 {DIVIDE 1729 &1274 BY 91} = 19/14.

@All,
Here is a shortcut.
Here you can simply divide No of PG(21% of 24700)/No of Grad.(14% of 27300),
since X:Y = X/Y.
After that, you will have an answer in decimal, which will be 1.357.
Now all you have to do is check the ratios in Option.
And the answer is, Option D, 19:14 = 19/14 = 1.357.

I would like to understand that what is actual method to calculate ratio,
Here I would like to add that 21*24700/14*27300 = to come different figure.
So please let me know that should be ideally calculated?

How or what quick method can we use or know that it is 273 that will divide 5187 and 3822 to give us 19:14. Quickest way of solving ratio?

24700 * 21/100 : 27300 * 14/100 = 19 : 14.
