Answer 1

I am not too sure about it

Answer 2

Answer:

Length of pole is 2 m

Step-by-step explanation:

Let length of pole be x  

According to question,

Pole has 20% of its length in mud 10% of its length in water and 1.4 metres above water, that is

20% x + 10% x + 1.4  = Total length

20% x + 10% x + 1.4  = x

0.2 x + 0.1 x + 1.4 = x

0.3 x + 1.4 = x

1.4 = x - 0.3 x

1.4 = 0.7  x

Dividing both the sides by 0.7,

1.4 / 0.7 = 0.7 x / 0.7

2 = x

x = 2 metres

Hence,

Length of pole is 2 m
