** ::
If 2/5 of a number exceeds 1/7 of the same number by 36.Find the number.​

Answer 1

Step-by-step explanation:

let the ni. be x

hence,

2x/5=x/7+36

2x/5-x/7=36

14x-5x/35=36

9x=36*35

9x=1260

x=1260/9=140

Answer 2

$let \: the \: number \: be \: x \\ \frac{2}{5} of \: the \: number \: be \: \frac{2x}{5} \\ \frac{1}{7} of \: the \: number \: be \: \frac{x}{7} \\ \\ ATQ \\ = > \frac{x}{7} + 36 = \frac{2x}{5} \\ = > \frac{x}{7} - \frac{2x}{5} = 36 \\ = > \frac{14x - 5x}{35} \\ = > \frac{9x}{35} = 36 \\ = > x = \frac{35\times 36}{9} \\ = > x = 140$
