Question

if 2/5 of a number exceeds 1/7 of the same number by 36 find the number​

Answer 1

Answer:

Step-by-step explanation:

Let the number be x

2/5 of the no. = (2x/5)

1/7 of the no. = (x/7)

It is given that 2x/5  exceeds  x/7  by  36

⇒ 2x/5  =  (x/7)+36

⇒ 2x/5  -  x/7  = 36

⇒ (14x - 5x)/35 = 36

⇒ 9x/35 = 36

⇒ 9x = 36×35

⇒ 9x = 1260

⇒ x = 1260/9

∴ x =140

∴The no. = 140

Answer 2

Answer:

140

Step-by-step explanation:

let the no. be x

=>(2/5)x - (1/7)x = 36

=>(14x - 5x) / 35 = 36

=>9x = 1260

=>x = 1260/9

=>x = 140
