Answer 1

Answer:

Let the salary of B be 100

Let the salary of A be 30% more than that of B,

\begin{gathered}\frac{100+30}{100}\times 100\\\\=Rs.130\end{gathered}

100

100+30

×100

=Rs.130

so, percentage is B's salary less than that of A's is given by

\begin{gathered}\frac{130-100}{130}\times 100\\\\=\frac{30}{130}\times 100\\\\=23.07\%\end{gathered}

130

130−100

×100

=

130

30

×100

=23.07%

• Hence, there is 23.07% B's salary is less than that of A's salary.
