Question

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

Answer 1

Answer:

2

5

2x−2

=5

2x−1

−100

shift 5

2x−2

to the left hand side

Now, Multiply the equation with -1

5

2x−1

−5

2x−2

=100

5

2x−2

(5−1)=100

5

2x−2

=

4

100

25

x−1

=25

( ∵ 5

2x−2

=(5

now,

x−1=1

x=2

Answer 2

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

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

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

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

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

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

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

$21a=20 \times 100$

$21a=2000$

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