10) 24,42,1/2,2,65,56,1 1/5,5/6.73,37
here we divide first no as tens digit divided by ons digit to get the third series no ie 2/4 =1/2
4/2 = 2 we get the forth no
it goes same and at last we get answer 7/3 = 2 1/3 ANS

Nishant Kumar  (9 years ago)

2) 41.45,41.5,42, 18.23,18.2,18
if we see in this all 3 pair are rounding and get the another value.
like 41.45 if we round the value we get 41.5
and if we round the value of 41.5 we get 42
next three pair is also the same
but to find the next no we can do like this i am not sure but i want your suggestion
41.45 - 5.00 as we round of 5.00 so we get the value 36.45 then divide it by 2 we get 18.23
now again 18.23 - 2.00 = 16.23 dividing by 2 we get 8.12
so

ANS is 8.12

Pratibha Rai  (7 years ago)

10) 24, 42, 1/2, 2, 65, 56, 1 1/5, 5/6, 73, 37, ?
=> group them i.e. (24, 42 ,1/2 ,2) , (65, 56, 1 1/5, 5/6) , (73, 37, ?)
We can see (24, 42) are reverse, similarly
(65, 56), (73,37)
=> 2/4 = 1/2 , swapping numerator no with denominator we get 2
(1/2, 2)
Similarly, 65= 6/5 = 1 1/5 and 5/6 i.e. (1 1/5, 5/6)
=> 73= 7/3 Ans
