A tailor needs 2/5th of a metre of cloth to make a flag. If a tailor has to make 400 flags, then cloth needed by tailor is

Options

A. 160m
B. 80m
C. 50m
D. 200m

Explanation

To determine the amount of cloth needed by the tailor to make 400 flags, we can follow these steps:

### Step 1: Identify the amount of cloth needed for one flag.
The problem states that the tailor needs \( \frac{2}{5} \) of a metre of cloth to make one flag.

### Step 2: Calculate the total cloth needed for 400 flags.
To find the total cloth needed for 400 flags, we multiply the amount of cloth needed for one flag by the number of flags:
\[ \text{Total cloth needed} = \left(\frac{2}{5}\right) \times 400 \]

### Step 3: Perform the multiplication.
First, we can simplify the multiplication:
\[ \frac{2}{5} \times 400 = \frac{2 \times 400}{5} \]
Calculating \( 2 \times 400 \):
\[ 2 \times 400 = 800 \]
Now divide 800 by 5:
\[ \frac{800}{5} = 160 \]

### Step 4: State the final answer.
The total amount of cloth needed by the tailor to make 400 flags is **160 metres**.
