Study the following information carefully and answer the questions.No...
(iv) The number of non defective Normal phones sold which went to the service center is 1/12 of the number of non defective Normal phones sold.
1/12 of the number of non defective Normal phones sold = 110400
The number of non defective Normal phones sold = 110400 × 12 = 1324800 Eq.(1)
The number of non defective Normal phones sold which did not go to the service center = 1324800-110400
= 1214400
(v) The number of non defective Normal phones sold which did not go to the service center is 3274350 less than the number of non defective Smartphones sold which did not go to the service center.
1214400 = non defective Smartphones sold which did not go to the service center - 3274350
Non defective Smartphones sold which did not go to the service center = 1214400 + 3274350
= 4488750
(vii) The ratio between the Number of non defective Smartphones sold which went to the service center to the Number of non defective Smartphones sold which did not go to the service center is 1 : 7 respectively.
Number of Non defective Smartphones sold which did not go to the service center = 7a = 4488750
Number of non defective Smartphones sold which went to the service center = a = 641250
Number of non defective Smartphones sold = 8a = 5130000
(vi) 5% of the number of non defective Smartphones manufactured are unsold.
Number of non defective Smartphones manufactured are sold = (100 - 5)% = 5130000
95% = 5130000
1% = 54000
Number of non defective Smartphones manufactured = 100% = 5400000
Number of non defective Smartphones manufactured are unsold = 5400000-5130000
= 270000
(ii) 83.33% of the number of Smartphones manufactured are non defective.
Number of non defective Smartphones manufactured = 5/6 = 5400000
Number of Smartphones manufactured = 6480000
Number of defective Smartphones manufactured = 6480000 - 5400000
= 1080000
(i) The ratio between the number of Smartphones manufactured to the number of Normal phones manufactured is 3 : 1 respectively.
Number of Smartphones manufactured = 3b = 6480000
Number of Normal phones manufactured = b = 2160000
Total number of phones manufactured = 6480000+2160000
= 8640000
(iii) 33.33% of the number of Normal phones manufactured are defective.
Number of defective Normal phones manufactured = 2160000 of 1/3
= 720000
Number of non defective Normal phones manufactured = 2160000 - 720000
= 1440000 Eq.(2)
The number of non defective Normal phones unsold = Eq.(2) - Eq.(1) = 1440000 - 1324800
= 115200
Hence, option d is the correct answer.
