85,000

71,000

91,000

81,000

93,000

Solution:

Required answer = 85 × 240 + 88 × 300 + 95 × 360

= 81000

= 81000

**Q5. What is the ratio of good headphones in 2013 to that in 2015?**

10 : 13

11 : 13

15 : 11

11 : 15

**Q6. If the average of 5 consecutive odd numbers is 35. Find the product of smallest and second highest number.**

1147

1121

1113

1127

1215

Solution:

Avg. of 5 odd no. is = 35

Let a = 35

∴ smallest no. among them = a – 4

= 35 – 4

= 31

Second highest among them = a + 2

= 35 + 2

= 37

∴ Reqd. answer = 31 × 37 = 1147

Let a = 35

∴ smallest no. among them = a – 4

= 35 – 4

= 31

Second highest among them = a + 2

= 35 + 2

= 37

∴ Reqd. answer = 31 × 37 = 1147

Total letter in word CAMEL = 5

∴ Required no. of ways = 5! = 120

∴ Required no. of ways = 5! = 120
