6-3 11-5 19-10 30-18
3 6 9 12
like that 29+15=44
3........a-c =b
a-25=b then we get 99

- 0.2*160=32, 0.5*30=15, 0.7*40=28
answer=40 - 9 years agoHelpfull: Yes(5) No(0)
- 3)33,8,41,46,21,67,72,47,119,124,73,197
33+8=41
46+21=67
72+47=119
124+73=197
y iam choosing 197 bcoz........
the diff bwn 41 & 67 is 26
n d diff bwn 67 & 119 is 52 (i.e 2*26)
so d diff bwn 119 & 197 is 78 (i.e 3*26)
so 73 added to 124 for 197 - 9 years agoHelpfull: Yes(2) No(2)

Solution:
41-33=8
67-46=21
119-72=47
?-124=?
So here 8+13=21 (here Series of 13 is added)
21+26=47
47+39=86
Now 41-33=8
67-46=21
119-72=47
210-124=86
so ans is 124,86,210 - 9 years agoHelpfull: Yes(0) No(1)
- 0.2 * 160 =32
0.5 * 30 =15
.......
0.7 *40 =28
so ans is 40 - 9 years agoHelpfull: Yes(0) No(0)
- 160*0.2=30

- 1st number is the multiplication of 2nd and 3rd number=>160*0.2=32
4th number is the multiplication of 5th and 6th number=>30*0.5=15
same as=0.7*40=28...
so ans is 40
