There are two categories of Pasta: Veg and Nonveg in a restaurant. In both Veg and Non- veg there are again two varieties:red sauce and white Sauce. In the veg category, people either like red sauce or white sauce or both and similarly in the non-veg category also.
Veg:The ratio of the number of people who like red sauce pasta to the number of people who like only white sauce pasta is 3: 4 and the number of people who like only red sauce pasta is 30 more than the number of people who like both red sauce and white sauce pasta together. Nonveg:Total number of people who like white sauce pasta is 80 which is equal to the number of people who like only veg white sauce pasta. The total number of people who like non-veg pasta is 40 less than the total number of people who like veg pasta. The number of people who like only red sauce pasta is 40% of the number of people who like only white sauce pasta.

d) 225
e) 200
Total people who have veg pasta at the

b) 66 (2/3)%
c) 73 (1/3)%
d) 57 (2/7)%
e) 48 (2/9)%
Total persons who like both red sauce pasta and
white sauce pasta together = 15 + 30 = 45
Required percent = (30/45) * 100 = 66 (2/3)%
b) 50%
c) 60%
d) 80%
e) 75%
Total number of people who like veg red sauce
pasta = 60
Total number of people who like nonveg white

Total number of persons who like veg and
