Directions (Q. 6 – 10):
The percentage of people eat both veg and non-veg items = 15 %
The percentage of people eat only Veg items = 62 – 15 = 47 %
The percentage of people eat only Non-veg items = 100 – 15 – 47 = 38 %
According to the question,
(47 % – 38 %) of total people went for hotel = 36
9 % of total people went for hotel = 36
Total people went for hotel = 36 * (100 / 9) = 400
Total number of people eat only Veg items = 400 * (47/100) = 188
Total number of people eat only Non-veg items = 400 * (38/100) = 152
Total number of people eat both Veg and Non-veg items
= > 400 * (15/100) = 60
6) Answer: B
Total number of people eat only Veg items
= > 400 * (47/100) = 188

Total number of people eat both Veg and Non-veg items
= > 400 * (15/100) = 60
175 % of total number of people eat both veg and non-veg items
= > 60 * (175/100) = 105
8) Answer: A
The total number of people eat only veg items = 188

Required ratio = 62: 53
10) Answer: B
