Question

Six-sevenths of a number is 36. Find the number. ( A ) 49 ( B ) 45 ( C ) 42 ( D ) 48

Answer 1

Answer:

Let the required number be x.

$\: \: \: \: \: \: \: \: \: \frac{6}{7} \: of \: x = 36$

$= > \frac{6}{7} \times x = 36$

$= > \frac{6x}{7} = 36$

$= > 6x = 7 \times 36$

$= > x = \frac{7 \times 36}{6}$

$= > x = 7 \times 6$

$= > x = 42$

Hence, the required number is 42.

Option (C) is correct.
