8.8 minutes

14 minutes

10 minutes

Data inadequate

None of these

Solution:

Let inlet pipe B takes x minutes to fill the cistern

ATQ,

x-x/4=33

⇒ x = 44 min.

∴ One minute’s work of A & B both

=1/11+1/44

=5/44

∴ Required time=44/5=8.8 min.

ATQ,

x-x/4=33

⇒ x = 44 min.

∴ One minute’s work of A & B both

=1/11+1/44

=5/44

∴ Required time=44/5=8.8 min.

16 years

15 years

17.5 years

19 years

16.5 years

Solution:

Let average age of 60 girls is x and age of new girl is y

∴(60x-25+y)/60=x-1.5/12

⇒ –25 +y = –7.5

⇒ y = 17.5 years

∴(60x-25+y)/60=x-1.5/12

⇒ –25 +y = –7.5

⇒ y = 17.5 years

**Directions (11-15): Study the following pie charts and answer the related questions.**
