A survey was conducted among 600 CAT 2012 aspirants to gauge the popularity of four different Test Series – T1, T2, T3 and T4. It was found that the number of aspirants who had joined T1, T2, T3 and T4 was 209, 217, 288 and 284 respectively. It is also known that: (i) The number of aspirants who had joined T1, T2 and T3 but not T4 was equal to that of those who had joined T1, T2 and T4 but not T3, which, in turn, was 2 less than that of those who had joined all the four Test Series. (ii) The number of aspirants who had joined only T1, only T2, only T3 and only T4 was 30, 30, 80 and 60 respectively. (iii) The number of aspirants who had joined exactly three of the four Test Series was 100. (iv) The number of aspirants who had joined both T1 and T3 but neither T2 nor T4 was 5 less than that of those who had joined both T1 and T4 but neither T2 nor T3. (v) The number of aspirants who had joined both T3 and T4 but not T2 was equal to that of those who had joined both T3 and T4 but not T1. (vi) The number of aspirants who had joined both T1 and T2 was 96 and that of those who had joined both T1 and T2 but neither T3 nor T4 was 28. (vii) The number of aspirants who had joined both T3 and T4 but neither T1 nor T2 was 55.

In a factory, there are equal number of women and children. Women work for 6 hours a day an children and 4 hours a day. During festival time, the work load goes up by 50%. The government rule does not allow children to work for more than 6 hours a day. If they are equally efficient and the extra work is done by women, then extra hours of work put in by women every day are
4
9
5
3
women work for 6hours a day that is 1/6 = 16.67%
children work for 4 hours a day = 25%
In festive season work has increased up to 50 % so children will work for 6 hours a day according to govt rule that is 1/6 = 16.67% and the rest has to contribute it by the women to make 50% she has to do 1/3 = 33.33%
16.67 + 33.33% = 50%
so women work for 3 hours extra
