Question 877970
This is the question i wanted to ask:
'I am a number between 20 and 30.If you divide 71 and 94 by me,the remainder is 2.What the number? 
let us subtract 2(remainder) from two given number  71 and 94
new number will be 69     and    92
take HCF  of  69 and 92
69= 23x3
92 = 23x2x2
HCF common is 23 
therefor HCF is 23 which is lies between 20 and 30 
so 23 is the number which if divide 71 and 94  there will be 2 remainder 
Answer 23
