94 is divided into two parts in such a way that the fifth part of the first and the eighth part of the second are in the ratio 3 : 4. The first part is :
94 is divided into two parts in such a way that the fifth part of the first and the eighth part of the second are in the ratio 3 : 4. The first part is :
[A]28
[B]30
[C]36
[D]40
30
First part = x
and second part = 94 – x
$latex \therefore \frac{\frac{x}{5}}{\frac{94-x}{8}} = \frac{3}{4}&s=1$
$latex => \frac{x}{5}\times \frac{8}{\left ( 94-x \right )}= \frac{3}{4}&s=1$
$latex => 32x = 15\times 94 – 15x$
$latex => 47x = 15\times 94$
$latex => x = \frac{15\times 94}{47} = 30&s=1$
Hence option [B] is correct answer.
