Following bar graph represents the sale of wired and wireless earphones (in numbers) in company K, L, M and N.

Sale of earphones = sale of wired earphones + sale of wireless earphones

Ques : What is the ratio of sale of earphones in company M to the sale of wireless earphones in company K and N together?

Correct Answer: (d) 13 : 11
Solution:

From the graph, we have

Company

Sale of wired earphones

Sale of wireless earphones

K

800

350

L

650

600

M

450

850

N

950

750

 

Sale of earphones in company M = 450 + 850 = 1300
And the sale of wireless earphones in company K and N together = 1100
Therefore, ratio = 1300 : 1100 = 13 : 11

172. If the ratio of production to sale of wired earphones and wireless earphones in company L are 19 : 13 and 3 : 2 respectively, then find the production of earphones in company L.

Correct Answer: (b) 1850
Solution:In company L:
Production of wired earphones = 650 × 19/13 = 950
Production of wireless earphones = 600 × 3/2 = 900
Therefore, production of wired and wireless earphones = 950 + 900 = 1850

173. If the average sale of wireless earphones in company L, M and P is 550, then how many wireless earphones sold from company K and P together?

Correct Answer: (a) 650
Solution:Sale of wireless earphones in company L = 600
Sale of wireless earphones in company N = 750
Then, the sale of wireless earphones in company P = 3 × 550 - 600 - 750 = 300
Sale of wireless earphones in company K = 350
Therefore, the sale of wireless earphones in company K and P together = 350 + 300 = 650

174. In company N, if the sale of earphones is 32% less than that of sale of headphones, then the sale of wireless earphones in company N is what percentage of sale of headphones in the same company?

Correct Answer: (d) 30%
Solution:In company N:
Sale of earphones = 950 + 750 = 1700
Then, sale of headphones = 1700 × 100/(100 - 32) = 2500
Now, sale of wireless earphones = 750
Therefore, required percentage = (750/2500) × 100 = 30%

175. What is the difference between the sale of wired earphones in company K and M together and the sale of wireless earphones in company M?

Correct Answer: (c) 400
Solution:Sale of wired earphones in company K and M together = 800 + 450 = 1250
And the sale of wireless earphones in company M = 850
Therefore, difference = 1250 - 850 = 400
