Question

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

Answer 1

Step-by-step explanation:

In all such questions, always remember that your first step should be the assumption of a variable.

Let the number be 'x'.

Now according to the statement in the question, we can simply form the following equation,

$\frac{2}{5} x - \frac{1}{7} x = 36$

Solving LHS,

$\frac{14x - 5x}{35} = 36 \\ \\ = > \frac{11x}{35} = 36 \\ \\ = > 11x = 36 \times 35 \\ = > x = \frac{1260}{11} \\ \\ = >x = 114 \frac{6}{11}$

Required number = $114 \frac{6}{11}$

Answer:

$114 \frac{6}{11}$

Answer 2

let the number be x .

2/5x-1/7x =36

(14x-5x)/35=36

x=36×35/9

x=35×4

x=140
