➡ A number is decreased by 40 % it results 135

Let's assume the number as x :

According to the question :

$\sf : \implies \: x - (x \: of \: 40\%) = 135 \\ \sf : \implies \: x - \frac{2x}{5} = 135 \\ \sf : \implies \: \frac{3x}{5} = 135 \\ \sf : \implies \: x = \frac{135 \times 5}{3} \\ \sf : \implies \: x = 225 \: ans.$
