Logic to get the answer is switch numerator digits For example :- 21/6 = 2 Write it as 12/6 = 2

For 27/9, switch numerator digits as 72/9 = 8 Ans :- 8

Here the numbers in the numerator should be interchanged like for example in 21/6 make numerator as 12/6 you will get 2..similarly 12/7 make 21/7=3 65/8 make 56/8=7 Then 27/9 make 72/9=8... Ans is 8

2*6=12 =>21 3*7=21 =>12 7*8=56 =>65 8*9=72 =>27 Answer is 8.

That was really a sad thing that students has been facing this issue with undocumented procedures. I really feel it's the time for them to consider their requests and make them get what they need regarding writing. Well even I buy research paper depending on my own analysis and never make such mistakes.

if 3+4=21 , 5+6=55 , 2+7=18 then how much is 6+8=?
