A pole is painted yellow and black. The yellow part is $1.8m$ long and the black is three times longer than yellow part. Find the length of pole.

• A. $5.4m$
• B. $7.2m$
• C. $3.6m$
• D. $noneofthese$

Answer 1

The correct option is B $7.2m$

Length of Black Part $=3Y=5.4m=B$

So, Length of Pole $=L=Y+B=1.8+5.4=7.2m$
