Question

If A's weight is 40% less than that of B, how much percent B's weight is more than that of A?

Answer 1

Answer:

60%

Step-by-step explanation:

A weight = 40%

So 100% - 40%= 60%

60% is b weight

Answer 2

• As per the data given in the data, we have to determine that B's weight is more than that of A.

          Given data:- A's weight is $40\%.$.

          To find:- Find B's weight$=?.$

          Solution:-

• A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.

• It is denoted by means $\%.$ $1\%.$  

• We are using the unitary method to calculate the percentage of numbers.

• Fractions can be converted into percentages and vice-versa.

• Percentages are reversible. For example,  $30\%$ of $40$ is the same as  $40\%$ of $30$ .

     Let B's weight  $kg=100$

     Then A's weight $=$  B's weight $-$ $40\%$ of B's weight

     A's weight is

             $100-\frac{40}{100}\times100\\=100-40\\=60$

    now B's weight is $40kg$ more than A

         $=\frac{40}{60} \times100\\=66.66\%.$

    Hence $66.66\%$ B's weight is more than A.
