Math, asked by suvin06, 1 year ago

2+7=34
8+9=18
6+3=78,then 
5+7=?



suvin06: sir tell me quick.............
kvnmurty: perhaps:
2 + 7 means 2 * (10+7) = 34
6 + 3 6 * (10+3) = 78
then 5 + 7 could mean 5 * (10+7) = 85
But 8 + 9 is not fitting in this pattern.
Anonymous: I think suvin has done a mistake in the question.
kvnmurty: possible. thanx

among four given options 8+9=18 it is given as 8+9=17 and add one to it then it is 17+1=18
like in the same way 5+7=13 it is given as 5+7=12 and add one to it then it is 12+1=13
but when u compared with first option and third option the answer can be given as
5+7=85
because replace 7 with 17 then multiply with 5 ie 17*5=85 
because 2+7=34
how in the sense replace 7 with 17 multiply with 2 therefore 2*17=34
like same way third option
6*13=78 i.e replace 3 with 13 and multiply with 6
so the final answers are 13 and 85
