centage increase in his salary :​

Answer 1

Given :

• Krishna's salary = Rs. 16,000 per month
• Increase in salary = Rs. 800 per month

To Find :

• Increase percentage in his salary = ?

Solution :

We have :

• Original salary = Rs. 16,000
• Increase in amount = Rs. 800

So, to find percentage increase, we have a formula :

$\underline{\boxed{\bf{Percentage \: increased = \dfrac{Increase \: in \: amount}{Original \: salary} \times 100 \%}}}$

By filling values :

$\sf : \implies Percentage \: increased = \dfrac{Rs. \: 800}{Rs. \: 16,000} \times 100 \%$

$\sf : \implies Percentage \: increased = \dfrac{Rs. \: 800}{Rs. \: 16,0\cancel{00}} \times 1\cancel{00} \%$

$\sf : \implies Percentage \: increased = \dfrac{80\cancel{0}}{16\cancel{0}} \%$

$\sf : \implies Percentage \: increased = \cancel{\dfrac{80}{16}} \%$

$\sf : \implies Percentage \: increased = 5 \%$

$\large \underline{\boxed{\bf{Percentage \: increased = 5 \%}}}$

Hence, 5% is the percentage increased in his salary.
