5:8
5+t: 8-t= 7:6
total number of marbles 5+8 ( k)
Quote:
(1) Initially the number of marbles in box Y was between 45 and 100.
multiple of 8 over 45 and less than 100
48,56,64,72,80,88,96
it means
marbles in X can be
30,35,40,45,50,55,60
if a movement is done between x and y then
case1: 48.7-6.30= 153
30/48 moverment of 12 marbles can be make the desired ration
x+y=78
case2: 35/56
7.56-6.35 = 392-210 = 182
14 marbles can be exchanged
x+y= 91
case3:-40.6+64.7= 448-128-
16 marbles can be exchanged
case4: 7.72-6.45=144 -
18 marbes
case5 :7.80-6.50=560-300=160
20 marbles
=
case 6:7.88-6.55= > 22 marbles
=
case7 :7.96-6.60=> 24 marbles
NOT SUFFICIENTQuote:
(2) After the transfer, the number of marbles in box X became between 45 and 100.
after the transfer values can be
new X can be only = 49,56, 63, 70,77,84,91,97
it means new Y was= 42,48, 54, 60,66,72, 78,84,
transfer values would be = (49.8-42.5)..............(97.8-85.5)
14,16,18,20,22,22,24...26,
original X comes out to be= 35,40,45,50,55,60,65,70
original Y comes out to be = 56, 64, 72,80,88,96,xxx
x+y has multiple values
NOT SUFFICIENTQuote:
combine 1 and 2
common values
original x= 35,40,45,50
original y= 42,48,54 ,60
still there are mutile valuesNOT SUFFICIENThence together also not sufficient
final answer: E
