Answer:

140

Step-by-step explanation:

Let the number be x.

2/5th of a number or x is 2x/5.

1/7th of the number or x is x/7.

The problem says 2/5th of x or 2x/5 exceeds 1/7th of the same number which means x/7 by 36.

so , according to the problem

 2x/5 -x/7=36

To compute this we need to find L.C.M of 5 and 7 which is actually the product of these two number in this case.

so 5*7 =35

  (2x*7 - x*5)/ 35 =36

Product of 2x *7 comes down to 35 and product of x*5 is 5x.

so, (14x-5x)/35= 36

     9x/35 = 36

By taking 35 to R.H.S it gets multiplied to 36.

so, 9x= 36 * 35

    x= (36* 35)/9

    x= 4* 35

    x= 140.

Hence the number given here is 140.
