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:

STEP 1: Find the percentage of the pole above water:

Length = 100 - 20 - 10

Length = 70%

STEP 2: Find 1% of the length of the pole:

70% = 1.4 m

1% = 1.4 ÷ 70

1% = 0.02 m

STEP 3: Find 100% of the length of the pole:

1% = 0.02 m

100% = 0.02 x 100

100% = 2 m

Answer: The pole is 2 m long
