Dont like to read =a
like to read = b
statement 1
a= 110
Those who like to read can never be 70 as a= 110
hence statement 1 sufficient
statement 2
x= 480
those who dont like to watch movie and dont like to read = (1/6) * 480 = 80
those who dont like to read can never be 70
hence statement 2 is sufficient
answer is D option
Dont you think you have reversed like to read and dont like to read , like movies and dont like movies ?.
Also can you pls explain this statment
statement 1
a= 110
Those who like to read can never be 70 as a= 110
hence statement 1 sufficient
yes! you are right I jumbled the whole answer.
But now as I was attempting this question again. Here is the new solution.
Total respondents = x
dont like movie = 1/4 x
dont like to read = 1/6 x
like to read = 1/12 x
like movies = 3/4 x
dont like to read = a
like to read = b
to find = 1/6 x + a
statement 1
b = 110
a = 3/4 x - 110
now what we have to find is 1/6 x + a = 70
1/6 x + 3/4 x - 110 = 70
11/12 x = 180
( x is coming in decimal which cant be the case as x should always be the natural number)
hence statement 1 is sufficient ( please do tell whether my thought process is correct)
statement 2
total respondent = 480
dont like to read and dont like movies = 1/6 x= 80
and the one who dont like to read can never be 70
statement 2 sufficient
hence option D
