vandana  (2 year ago)

According to me the answer option should be (c)
Reason :
Let there be 100 ml of water and 100 ml of coffee initially .
wc = water content
cc = coffee content

First tumbler Second Tumbler
wc cc wc cc
initially 100 0 0 100
after 1 move 99 0 1 100

1 spoon of second tumbler now contain 1/101 water and 100/101 of coffee

after second move

First tumbler Second Tumbler
wc cc wc cc
after second move 99+1/101 100/101 1-1/101 100-100/101
= 10000/101 100/101 100/101 10000/101

So answer option (c) ..

1st trumbler
w=10 c=0
2nd trumbler
w=0 c=10
After 1st mooving
1st trumbler
w=9 c=0
2nd trumbler
w=1 c=10
during moving mixture from 2nd one to 1st one
one spn contain w=1/11,c=10/11
1st trumbler
w=(9+1/11)=100/11
c=10/11*****
2nd trumbler
w=(1-1/11)=10/11*****
c=10-10/11=100/11
So ans is 'c'

Rupkatha Nag  (2 year ago)

ans:)There is less coffee in the first tumbler than milk in the second tumbler
This is because when we pour a glass of milk in the tumbler of coffee,we are getting a 100% pure content of milk in the coffee.But when we put a glass of this mixture in the tumbler of milk then we don't get pure coffee in it but a mixture which contains some portion of milk also.Thus there is less coffee in the first tumbler than milk in the second tumbler.

animesh paul  (2 year ago)

#there is as much coffee in the first tumbler as there is milk in the second tumbler.# :)
suppose in 1st tumbler 100w(water)
in 2nd tumbler 100m(milk)

let us take 1 glass=10
thus after removing 1 glass from 1st tumbler..
in 1st tumbler=90w
in 2nd tumbler=100m+10w
thus ratio of milk to water in 2nd tumbler=10:1

now we remove 1 glass from the 2nd tumbler
thus milk removed to glass 1=(10/11)*10=100/11m
water removed=(1/11)*10=10/11w

thus water in 1st tumbler=10/11w+90w=90.9w
milk in 1st tumbler=100/11m=9.09m

now milk in 2nd tumbler=100m-9.09m=90.9m
water in 2nd tumbler=10w-10/11w=1
