Question

A batch has 15000 coloured bulbs. 3/5 of the batch are orange in colour & the rest are green . if 1/8 th of the green bulbs are not working , how many green bulbs are functional?

Answer 1

5250 bulbs are functional green bulbs

Explanation:

find out how much 1/5 of 15000 is

15000/5=3000

find out how many are orange

3/5=1/5+1/5+1/5 3000*3=9000

of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over

15000-9000=6000 bulbs are green

find out what 1/8 of the green bulbs is

6000/8=750

1/8 or 750 green bulbs are not working

find out how many bulbs are functional

6000-750=5250 bulbs are functional green bulbs
