-
- 1)ans 2
7/6+1=13/6
3/2+1=5/2
1+1=2 so on - 10 years agoHelpfull: Yes(24) No(5)
- 2) Series:5,6,6.5,6.5,8,7,9.5,?
Two Series 5,6.5,8,9.5 (Common difference 1.5)and 6,6.5,7,?(Common difference 0.5)
6+0.5=6.5
6.5+0.5=7
7+0.5=7.5 Ans
- 10 years agoHelpfull: Yes(5) No(3)
- 1.next no wuld be 12/6,11/6
- 10 years agoHelpfull: Yes(4) No(2)
- 1.(7/6,3/2,1,5/6),(7/6+1,3/2+1,1+1,5/6+1)
so, ans=2
2. actual series: 5,6,6.5,6.5,8,7,9.5
two series: 5,6.5,8,9.5 having diff 1.5 and 6,6.5,7,7.5 having diff .5
ans= 7.5
- 10 years agoHelpfull: Yes(3) No(0)
- 2. I THINK THE ANS WILL BE 12
there is sumthing wrong bin this series.. - 10 years agoHelpfull: Yes(2) No(2)
- (1) (7/6,5/6,x) (3/2,13/6) (1,5/2)
x=3/6
(2) 5,5+1=6,6+0(1)=6 1
5,5+1.5=6.5,6.5+1(1.5)=8 1+.5=1.5
7,7+2.5=9.5,9.5+2(2.5)=14.5 1.5+1=2.5
(3) 1/5,1/2,1/3,2/5,1 2/3,3/5,1 1/2,1 4/5
- 10 years agoHelpfull: Yes(0) No(0)
- 3)1/5,2/5,3/5 and ultimately next will be 4/5
- 8 years agoHelpfull: Yes(0) No(1)
- Ans(1) -> 7/6 , 3/2 , 1 , 5/6 , 13/6 , 5/2 . . . .
=>This series is the combination of four different series
1 ) -> 7/6 , 13/6 , 19/6 . . . . . .
2) -> 3/2 , 5/2 , 7/2 . . . .
3) -> 1 , 2 , 3 , 4 , 5
4) -> 5/6 , 11/6 . . . . .
so combine all 4 series
7/6 , 3/2 , 1 , 5/6 , 13/6 , 5/2 , 2 , 11/6 . . . . . . .
so the answer is 2 and another next term 11/6 - 7 years agoHelpfull: Yes(0) No(0)
IBM Other Question
8,.5,16,4,15,.3,50,4.5,6,.2,30
In a computer institute 9 languages can be taught. The module is of 6 months duration and of six languages only one can be taught each month. In addition to that BASIC is always taught and should be in first month itself WORD PERFECT is to be taught in the preceeding week of WORD STAR. FORTRAN cannot be taught until cobol is taught prior to that BINO,FIFO cannot be taught in single module languages are BASIC, COBOL, FORTRAN, WORD PERFECT, WORD STAR, LOTUS, C, BINO, FIFO.
1)IF WORDSTAR is in 3rd month what could taught in 6th month.
2)if COBOL is in 2nd month and BINO in 6th month ,FORTRAN will be taught in which month ?
