Answer 1

HEY MATE !!!

Let the number be x

According to the question,

$( \frac{1}{7} \times x) - ( \frac{1}{11} \times x) = 100 \\ \\ \frac{x}{7} - \frac{x}{11} = 100 \\ \\ \frac{11x - 7x}{77} = 100 \\ \\ \frac{4x}{77} = 100 \\ \\ 4x = 77 \times 100 \\ \\ x = \frac{77 \times 100}{4} \\ \\ x = 77 \times 25 \\ x = 1925$

Thus the number is 1925
