The result of annumber when decrease is 30%is147 what is the number

Answer 1

Explanation:

let the number is m

So , m - 30% of m = 147

$m - \frac{30}{100} \times m = 147 \\ \frac{100m - 30m}{100} = 147 \\ \frac{70m}{100} = {147} \\ \frac{m}{10} = 21 \\ m = 210$

therefore the number is 210 .

Answer 2

Answer:

Explanation:

let the number is m

So , m - 30% of m = 147

\begin{gathered}m - \frac{30}{100} \times m = 147 \\ \frac{100m - 30m}{100} = 147 \\ \frac{70m}{100} = {147} \\ \frac{m}{10} = 21 \\ m = 210\end{gathered}

m−

100

×m=147100

100m−30m =14710070m =14710m =21m=210

therefore the number is 210 .
