Question

Copy and complete this table.

$100 %$	$30$	$2500$
$120 %$
$12.5 %$				$6$
$0.5 %$			$4$

Accepted Answer

The given table is :

$100 %$ $30$ $2500$

$120 %$

$12.5 %$ $6$

$0.5 %$ $4$

We observe in the first column,

$100 % = 30$

$\Rightarrow 1 %$ of $30 = \frac{1}{100} \times 30 = 0.3$

$\Rightarrow 120 %$ of $30$ $= 120 \times 0.3 = 36$

$12.5 %$ of $30 = 12.5 \times 0.3 = 3.75$

$0.5 %$ of $30 = 0.5 \times 0.3 = 0.15$

In the second column,

$100 % = 2500$

$\Rightarrow 1 %$ of $2500 = \frac{1}{100} \times 2500 = 25$

$\Rightarrow 120 %$ of $2500$ $= 120 \times 25 = 3000$

$12.5 %$ of $2500 = 12.5 \times 25 = 312.5$

$0.5 %$ of $2500 = 0.5 \times 25 = 12.5$

Fourth column:

Let $100 % = x$

$\Rightarrow 12.5 % (x) = 6 \Rightarrow \frac{12.5}{100} \times x = 6 \Rightarrow x = \frac{46 \times 100}{12.5} = 368$

$\Rightarrow 1 % (368) = \frac{1}{100} \times 368 = 3.68$

$\Rightarrow 120 % (368) = 120 \times 3.68 = 441.6$

$0.5 % (368) = 0.5 \times 3.68 = 1.84$

Similarly, in the third column,

Let $100 % = x$

$\Rightarrow 0.5 % (x) = 4 \Rightarrow \frac{0.5}{100} \times x = 4 \Rightarrow x = 4 \times \frac{100}{0.5} = 800$

$1 % (800) = \frac{1}{100} \times 800 = 8 \Rightarrow 120 % ($ 800) = 120 \times 8 = 960 12.5 % (800) = 12.5 \times 8 = 100$

Putting all the values in the table, we get

$100 %$ $30$ $2500$ $800$ $368$

$120 %$ $36$ $3000$ $960$ $441.6$

$12.5 %$ $3.75$ $312.5$ $100$ $6$

$0.5 %$ $0.15$ $12.5$ $4$ $1.84$

Hence, this table is the required answer.
