Question

The annual salary of Suresh increased from 20,00,000 to 22,00,000. Find the percentage increase.

Answer 1

Answer :-

• The percentage increase is 10%.

To find :-

• The percentage increase.

Solution :-

• Before finding the percentage increase of Suresh, let's see how much did his salary increase!

Here,

• Original salary of Suresh = Rs 2000000.

• New salary of Suresh = Rs 2200000.

Hence :-

$\bf Increase = 2200000 - 2000000$

$\bf Increase = Rs \: 200000$

-----------------------------------

• Now, let's find the percentage increase!

We know that :-

$\underline{ \boxed{\sf Increase \: \% = \dfrac{Increase}{Original \: Amount}}}$

Here,

• Increase = Rs 200000.
• Original salary = Rs 2000000.

Therefore,

$\tt Increase \: \% = \dfrac{200000}{2000000} \times 100$

$\tt Increase \: \% = \dfrac{2 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0}{2 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0 \!\!\!\not0} \times 10 \!\!\!\not0$

$\tt Increase \: \% = \dfrac{2}{2} \times 10$

$\tt Increase \: \% = \cancel{\dfrac{20}{2}}$

$\overline{ \boxed{\tt Increase \: \% = 10\%}}$
