Step-by-step explanation:

let the electronic items purchased= 100

defective tv = 5% of colour tv

Answer 2

Answer:

3% of T.V.'s are defective

Step-by-step explanation:

Let total number of coloured T.V.'s be x

Number of coloured T.V.'s bought =60% of x=0.6x

Given that, 5% of these are defected.

⇒ Number of defective T.V.'s =5% of 0.6x

                                                  =  $\frac{5 X 6x}{1000}$

                                                  =0.03x

⇒3% of T.V.'s are defective
