HEY Buddy.....!! here is ur answer

$Let, \: the \: x \: girs \: are \: needed \\ \\ As\:we \: know \: that :\: \frac{m1 \times d1}{w1} = \frac{m2 \times d2}{w2} \\ \\ Here ,\: m1 = 9 \: d1 = 3 \: w1 = 135 \: d2 = 1 \: w2 = 270 \: and \: m2 = x \\ \\ = > \frac{9 \times 3}{135} = \frac{x \times 1}{270} \\ \\ = > x = \frac{9 \times 3 \times 270}{135} \\ \\ = > x = 54 \\ \\ Thus, \: there \: are \: 54 \: girls \: are \: needed \: to \: complete \: the \: work$
