# Data Interpretation - Pie Charts - Discussion

Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes: 1.

What percentage of candidates passed the Exam from institute T out of the total number of candidates enrolled from the same institute?

 [A]. 50% [B]. 62.5% [C]. 75% [D]. 80%

Explanation:

 Required percentage = 9% of 5700 x 100 % = 9 x 5700 x 100 % = 75%. 8% of 8550 8% of 8550

 Mallikarjun said: (Feb 9, 2011) Can you explain how it comes 9*5700/8%8550*100 (plz justify 8% of 8550)

 Ramesh Solanki said: (Mar 10, 2011) 8*100/8550=684

 Atin Gupta said: (Aug 6, 2011) @ malika arjun : Its quite simple divide what is the total and multiply what you are getting into 100.

 Abinash Agrawal said: (Sep 6, 2011) Can you give some formula to calculate percentage easily like. I divide 9*5700/8*8550 then it comes finally 57/76, to this its a lengthy process. Give some sort calculation formula.

 Nadhem Humash said: (Dec 2, 2011) (((9/100)*5700)/((8/100)*8500))/100=75%

 Vinoth.V said: (Nov 7, 2013) 10 percentage of 5700 is 570 how to calculate 9 percentage quickly?

 Hardik said: (Jan 20, 2014) 10%-1% = 9%. So, 5700*10% = 570. 5700*1% = 57. 570-57 = 513 or 5700*9/100 = 513.

 Dharani Kumar said: (Sep 26, 2014) {[(9% of 100)*5700/(8% of 100)*8550]*100}% = {[9/100*8*100*5700*8550]*100}%. ={[29/38]*100}%. = {0.76*100}%. = Approx 76%.

 Shaloo said: (Nov 19, 2014) Step 1: 9/360 x 5700 = 142.5. Step 2: 8/360 x 8550 = 190. Step 3: Percentage => 142.5/190 x 100 = 75%.

 Shaloo said: (Nov 19, 2014) Sorry since % is given, we cant take 360. Divide it by 100 i.e. Step 1: 9/100 x 5700 = 513. Step 2: 8/100 x 8550 = 684. Step 3: Percentage => 513/684 x 100 = 75%. If the values were in degree instead of %, divide them by 360 as shown before.

 Vishnu said: (Dec 1, 2014) Step 1: 9% of 5700. = (10%-1%) of 5700. = (10% of 5700) - (1% of 5700). = ((10/100) *5700) - ( (1/100) *5700). = 570-57. = 513. Step 2: Similarly, 8% of 8550 = 684. Step 3: Finally, 513/684 = 0.75. As we need percentage, multiply with 100 you will get 0.75*100 = 75%.

 Nithya Lingala said: (Jan 28, 2015) 9% of 5700 - 8%of 8550*100 = 75%.

 Purva said: (Jun 12, 2015) 9% of 5700 becomes 9% x 5700. But, 8% of 8550 remains the same. Why?

 Gajanan Naik said: (Jan 19, 2016) (9% of 5700)/(8% of 8550)*100 = ((9/100)*5700)/((8/100)*8550)*100. = (9*5700)/(8*8550)*100 = 0.75*100 = 75%

 Madhavi.K said: (Jan 19, 2016) 9*5700/8*8550 simplification for this. Step 1: 9% of 5700 = (10%-1%) of 5700 it becomes (10% of 5700-1% of 5700). = 570-57 = 513. Step 2: 8% of 8550 = (10%-2%) of 8550. It becomes (10% of 8550 - 2% of 8550). = 855+171 (i.e 41% of 8550 is 85.5. So 2% of 2500 is 85.5+85.5 = 171.0). Now last step is 513/684 = 0.75 (i.e 684) 51300 (0.75). It becomes 51300. Final step 0.75*100 = 75%.

 Pravi said: (Jan 14, 2017) Simple method. You get 57/76 which is further indivisible by single no. So now calculate as(5+7)/(7+6) which gives, 12/13 repeat one more time (1+2)/(1+3) equals 3/4 i.e 75%.
