Question

if one-seventh of a number exceeds its its eleventh part by 100 , then the number is:

Answer 1

Let the number be 'x'
1/7×x-x/11=100
x/7-x/11=100
(11x-7x)/77=100
4x/77=100
x=100×77/4
x=25×77
x=1925

Answer 2

Answer:

The number is =1925

Step-by-step explanation:

Let the number be =x , then according to the question, one-seventh of a number exceeds its its eleventh part by 100 that is

$\frac{x}{7}-\frac{x}{11}=100$

$\frac{11x-7x}{77}=100$

$4x=7700$

$x=\frac{7700}{4}$

$x=1925$

Thus, the number is =1925.
