Answers:

1. Answer: B

Number of mobile in A and B = 80 + 24 = 104

Number of watch sold in D and E = 111

Required percentage = 104/111 * 100 = 93.69% = 94%

2. Answer: B

Average number of pen drive = (40 + 62 + 54 + 10 + 74) / 5 = 48

Average number of laptop = (16 + 32 + 45 + 40 + 27) / 5 = 32

Difference = 48 – 32 = 16

3. Answer: B

Required ratio = (48 + 12):(64 + 32)

= 60:96

= 5:8

4. Answer: B

Total number of mobile sold in all the companies together = 80 + 24 + 48 + 12 + 36 = 200

Total revenue = 200 * 6000 = 1200000

5. Answer: C

Number of laptop = 16 + 32 + 40 + 45 + 27 = 160

Pen drive in A, B and E = 40 + 62 + 74 = 176

Difference = 176 – 160 = 16
