Question

0.4% of a number is 10 find the number​

Answer 1

†GIVEN†

• 0.4 of a number is 10

†TO FIND†

• The number .

†SOLUTION†

Let the required number be x then ,

$\color{black}\bold{A/q \: \: \: \: 0.4 \% \: of \: x = 10 }$

$\color{black}\bold{ \mapsto \: \frac{4}{1000} x = 10}$

$\color{black}\bold{ \mapsto \: x = \frac{10 \times 1000}{</u><u>4</u><u>} }{}$

$\color{black}\bold{ \mapsto \: x = 10 \times </u><u>2</u><u>5</u><u>0</u><u>}$

$\color{black}\bold{ \mapsto \: x =</u><u>2</u><u>5</u><u>0</u><u>0 }$

$\red{\mid{\fbox{\tt{</u><u>R</u><u>equired </u><u>\</u><u>:</u><u> number \:</u><u>=</u><u>\</u><u>:</u><u> </u><u>2</u><u>5</u><u>0</u><u>0</u><u>}}\mid}}$
