Question

A+(A*5/100) = 100 find the value of A​

Answer 1

$a + ( \frac{a \times 5}{100} ) = 100$

$a + ( \frac{5a}{100} ) = 100$

$a + ( \frac{a}{20} ) = 100$

$a + \frac{a}{20} = 100$

$\frac{20a + a}{20} = 100$

$\frac{21a}{20} = 100$

$20 \times \frac{21a}{20} =20 \times 100$

$21a=20 \times 100$

$21a=2000$

$a = \frac{2000}{21}$
