Ques - Out of a no. of electronics items, a person purchases 60% coloured TVs. 5% of these were found to be defective. The percentage of defective TVs in all is :
(a) 3%
(b) 6%
(c) 12%
(d) Can't be determined
Solution -
Let,
Total no. of TVs = 100
Number of purchased TVs = 60% of 100
Number of purchased TVs = 60
Number of Defective TVs = 5% of purchased TVs
Number of Defective TVs = (5/100) × 60
Number of Defective TVs = 3
Hence,
The percentage of defective TVs is 3%.
Thank You
