Solutions: (Qs.6 - 10): Total number of males from USA is 290 less than the number of female from same country who visited the Taj Mahal. Let total number of females from USA = X and number of male from USA = X − 290

X + X − 290 = 1710 accordingly X = 1000,

Key

6-c; Number of male and female from Germany who visited Taj Mahal = 720 + 1400 = 2120

7-e; Required ratio = 710 : 1440 = 71 : 144

8-d; Average number of Females from USA, Japan and Germany

a) 1 : 1               b) 2 : 3               c) 1 : 5             d) 1 : 3           e) None

Solutions (Qs. 11 - 15):

Persons who like Golgappa = 100 = A + B

Persons who like Chicken tikka = 120 = B + C

Persons who like none of these = 40

Persons who like exactly one of two items = 100 = A + C

2 (A + B + C) = 100 + 120 + 100 = 320

A + B + C = 160

A = 160 − 120 = 40

B = 160 − 100 = 60

C = 160 − 100 = 60

D = Persons who do not like any of two = 40

Key

11-d; People had like both the items = B = 60

12-b; Persons who does not like Chicken tikka
= Persons who like only Golgappa +
persons who like none of them = A = 40 +
40 = 80

13-d; Persons who like Only Golgappa A = 40

Persons who like Only Chicken tikka = B = 60

14-d; Required answer = C = 60

15-d; Required ratio = 40 : (60 + 60) = 40 : 120
= 1 : 3
