**Q6. Two pipes A and B together can fill a cistern in 4 hours. Had they been opened separately, then B would have taken 6 hours more than A to fill the cistern. How many time will be taken by A to fill the cistern separately?**

4 hours

2 hours

6 hours

8 hours

10 hours

**Q7. A tank can be filled by one tap in 20 min. and by another in 25 min. Both the taps are kept open for 5 min. and then the second tap is turned off. In how many more minutes is the tank completely filled?**

6 minutes

11 minutes

12 minutes

17 minutes

24 minutes

Solution:

LCM (20, 25) = 100 unit

A’s efficiency = 100/20 = 5 unit/ min

B’s efficiency = 100/25 = 4 unit/min

5 (A + B) + x.A = 100

5 (5 + 4) + x.5 = 100

45 + 5x = 100

5x = 55

⇒ x = 11 minute.

A’s efficiency = 100/20 = 5 unit/ min

B’s efficiency = 100/25 = 4 unit/min

5 (A + B) + x.A = 100

5 (5 + 4) + x.5 = 100

45 + 5x = 100

5x = 55

⇒ x = 11 minute.

**Q8. Find the lateral surface area of a regular pyramid with triangular base, if each edge of the base measures 8 cm and slant height is 5 cm**

**Q9. The number of ways in which a couple can sit around a table with 6 guests if the couple take consecutive seat is**

1440

720

5040

4440

1640

Solution:

Total no. of ways = (7 - 1)! × 2!

= 1440

= 1440

**Q10. A sink contains exactly 12 litres of water. If water is drained from the sink until it holds exactly 6 litres of water less than the quantity drained away, then how many litres of water were drained away?**

2 litres

6 litres

3 litres

9 litres

4 litres

Solution:

Let, required water to be drained out be x â„“

∴ x + x – 6 =12

⇒ x = 9 â„“

∴ x + x – 6 =12

⇒ x = 9 â„“

**Directions (11-15): Study the following graph carefully to answer the questions that follow: Number of bottles (in thousands) of three different companies in six different years**

**Q11. What was the percentage increase in bottles of company Milton in year 2004 as compared to that in the previous year?**

11.5%

11.25%

15.5%

12.5%

13.5%

**Q12. What was the difference between the number of bottles in all the three companies together in the year 2005 and the number of bottles in company Cello over all the years together?**

12000

11000

1100

1400

1200

Solution:

Required difference

= (5 + 4 + 7 + 6 + 4 + 7) ─ (8 + 6 + 7)

= 33 – 21

= 12 thousand

= (5 + 4 + 7 + 6 + 4 + 7) ─ (8 + 6 + 7)

= 33 – 21

= 12 thousand

**Q13. What was the approximate average number of bottles of Adidas company over all the years together?**

5999

5666

5444

5333

6555

**Q14. In which year was the number of bottles in all the three companies together the second highest?**

2003

2004

2005

2006

2007

Solution:

From the graph, it is clear that the second highest no. of bottles were in year 2005.

**Q15. Total number of bottles of Adidas and Cello companies together in the year 2007 was what percent of the total number of bottles of company Adidas in the year 2005?**

150%

120%

250%
