Let number of people in city C and D is 200d and 300d respectively.

Number of males who attend seminar from city C is

= 200d × [55/100] × [30/100] = 33d

Number of males who attend seminar from city D is

= 300d × [45/100] × [50/100] = 67.5d

So, 33d + 67.5d = 201

Or, d = 201 /100.5 = 2

Number of people who did not attend the seminar from D is

⇒ 55  200 × 2 /100 = 220  

Difference between male and female who did not attend the seminar from D is

⇒ 220 × 1 /11 = 20 = z

So, required value = 20 + 75 = 95
