- I think the question is wrong...!!!!!
- 11 years agoHelpfull: Yes(12) No(0)
- for Even places x/2 from the start
for Odd places x/3 from the end
EVEN places ODD Places
----------- ----------
48/2 = 24 90/3 = 30
24/2 = 12 30/3 = 10
- 11 years agoHelpfull: Yes(10) No(2)
- c)33
because in the series all no.s divisible by 3 and
in d options 33 is the only option divisible by 3.

- 3 ? 30 90
all that multiby 3
that and that no ans that 9
and that
10
ans 10 - 11 years agoHelpfull: Yes(6) No(7)
- moving from right to left alternatively and starting from 90:
90/3=30
30/3=10
10/3=3
ans=3 - 11 years agoHelpfull: Yes(6) No(12)
- Answer 10
3Rd no get it divided for 1st no by 2 for 48.
5th no get it divided for 3rd no by 2 for 24.
6th no get it multiple for 3 for the 4th no for 30
so 4th no is multiple for 3 for the 2nd no for 10
so answer 10

- 3*10=30
3*30=90
answer : 10 - 11 years agoHelpfull: Yes(3) No(0)
- 33 is the ans... bcz it is a multiple of 3
- 10 years agoHelpfull: Yes(2) No(1)
- 10 is the ans.
- 11 years agoHelpfull: Yes(1) No(0)
- All numbers are divisible by three except 33.
- 11 years agoHelpfull: Yes(1) No(8)
- The alternative numbers are decreasing/increasing from left to right
odd ones are decreasing by 1/3 and even ones are increasing as their double
so 90/3=30
30/3=10 - 11 years agoHelpfull: Yes(1) No(0)
- second sequence 48 24 12 i.e.., 48/2 =24 and 24/2 =12.
first aequence 3 ? 30 90
we get 3*10=30 and 3*30= 90 therfore ans is 10. - 11 years agoHelpfull: Yes(1) No(0)
- two series present
3,?,30,90
48,24,12
90/3=30 ,30/3=10 ,10/3=3.33 round 3 - 10 years agoHelpfull: Yes(1) No(0)
- ans is 10
Given series contains two series
3 , ? , 30 , 90
and
48 , 24 , 12
first series is multiple of 3 ie (3) , (3*3) , (10*3) , (30*3) but 9 is not in option and we to select one to we go for 10
second series is decreasing by x/2 - 9 years agoHelpfull: Yes(1) No(1)
- 90/3=30
30/3=10 - 8 years agoHelpfull: Yes(1) No(1)
- ans -10
3*3+3^0=10
9*3+3^1=30
27*3+3^2=90
and so on...............so ans will be 10. - 10 years agoHelpfull: Yes(0) No(0)
- ans=10 because.................
- 10 years agoHelpfull: Yes(0) No(1)
- we get 2 equation 3x-4y=5 and -5x+7y=6.So by solving we get x=11 and y=7
