Question

A number excedss its 5/7 by 16 find the number

Answer 1

$\mathbf{Let \: the \: number \: be \: K, }$


According to the question,


( 5 / 7 of K ) + 16 = K

$= > ( \frac{5}{7} \times K) + 16 = K \\ \\ \\ = > \frac{5K}{7} + 16 = K \\ \\ \\ => \frac{5K + 112}{7} = k \\ \\ \\ = > 5K + 112 =7 K \\ \\ \\ = > 112 = 2 K\\ \\ \\ => 56 = K$



Required number is 56

Hola Mate!!

Your answer :-

$let \: the \: number = x \\ \\ the \: equation \: becomes = > \\ \\ ↪ ( \frac{5}{7} \times \: x ) + 16 = x \\ \\ ↪ \frac{5}{7} x + 16 = x \\ \\ ↪ 16 = x - \frac{5}{7} x \\ \\ ↪ 16 = \frac{7x - 5x}{7} \\ \\ ↪ 16 = \frac{2}{7} x \\ \\ ↪ 16 \times \frac{7}{2} = x \\ \\ ↪ 56 = x$
