Question

40% of a pole is painted red, while 1/5th of the
remaining pole is painted white. Half of the
remaining pole is painted black. If the
remaining pole of 12 m is painted yellow, find
the length of the pole.​

Answer 1

Answer is :

50 metres

Step-by-step explanation:

40%= 40/100 = yellow

Remaining = 100-40 = 60

1/5of remaining = 1/5 * 60 = 12 = white

Remaining = 60-12 = 48

half of the remaining= 48/2 = 24 = black

remaining= 48-24= 24 which is 12 metres and is painted yellow

so it means

• 40% of the pole is yellow
• 12% = white
• 24%= black
• and remaining 24 % is yellow and is 12 metres

so if 24% is 12 meters

then 100% will be

24 = 12

100

12*100 = 1200/24 = 50

24

so length of pole is 50 metres
