Directions (Q. 6 â€“ 10):

The percentage of people eat both veg and non-veg items = 15 %

The percentage of people eat only Veg items = 62 â€“ 15 = 47 %

The percentage of people eat only Non-veg items = 100 â€“ 15 â€“ 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

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

The total number of people eat only veg items = 188

The total number of people eat only non-veg items = 152

Required difference = 188 â€“ 152 = 36

The total number of people eat veg items = 62 %

The total number of people eat non-veg items = 53 %

Required ratio = 62: 53

Total number of people eat only veg items = 188

Total number of people eat only non-veg items = 152

Required % = (188/152) * 100 = 123.68 % = 125 %
