Group between 30-49 is 25% in table 1 which represents 100% of table2

1. i need to find out minimum
( key point: the minimum number should not come as fraction)
minimum value given = 200.
so 25% would be 50 people.
lets see if any fraction in table 2 with 50 as total value ( in table 2 all are even numbers) so 200 is our answer

2. post graduate = 28% + doctorate = 8% in table 2 is 25% of total workers mention in table1
doctorate = 8%
so total post graduate+ doctorate % = 36/4= 9%
B is our answer
