Answer 2

Answer:

$New \: length\:of\:rope\\ =Rs\:131.25$

Step-by-step explanation:

Length of the rope (L)=150 m,

$Decrease (d)=\frac{25}{2}\% \\=12.5\%$

$New \: length=L\left(\frac{100-d}{100}\right)\\=150\left(\frac{100-12.5}{100}\right)\\=150\times \frac{87.5}{100}\\=\frac{13125}{100}\\=Rs\:131.25$

Therefore,

$New \: length\:of\:rope\\ =Rs\:131.25$
