Question

A pole has 20% of its length in mud, 10% of its length in water and 1.4 metres above water. The total length of the pole is

Answer 1

Answer:

2m

Step-by-step explanation:

Let length of pole be x

So

20% x + 10% x + 1.4 m = x

30%x+1.4 m=x

1.4 m=x-(3/10)x

1.4 m=(7/10)x

1.4*(10/7)=x

14/7=x

x=2m
