Answer 1

Heya....   ●●No.of defective bulbs out of 10 bulbs = 1 ●●The ratio of defective bulbs to the total ●●no.of bulbs = 1:10 ●●Total no.of bulbs produced = 630 ●●Let the no.of defective bulbs be x ●●Then the ratio is x:630 ●●Now 1:10 = x:630 ⇒10x =630 ⇒ x = 630/10 ∴ x = 63 ∴The no.of defective bulbs = 63    @skb

Answer 2

electric bulb in 1 day=630
no. of defective bulb in 1 day =630 /100
=63
hence the total no. of defective bulb is 63.
