Question

1/5 of a number exceeds 1/7 of the same number by 10.the number is

Answer 1

Let the no. be x. Then,
x/5= 10 + x/7
Taking the LCM on RHS,
x/5 = ( 70 + x)/ 7
Cross multiplying,
7x = 350 + 5x
2x = 350
x = 175

Answer 2

hi

let the number be x

1/5 of a number exceeds 1/7 of the same number by 10

so,

lets form an euqation

1x/5 = 1x/7 +10

1x/5 - 1x/7 = 10

lcm = 35

7x-5x/35 = 10

2x/35 = 10

x = 35*10/2

=>x = 35*5

x = 175

hope it helps u
