Answer 2

Given: $30$% of a number is $63$less by three fourth of that number.

We have to find the number.

We are solving in the following way:

We have,

$30$% of a number is $63$less by three fourth of that number.

Let assume the number will be$x$.

Then, from the given statement we can write:

$30\%\ of\ x=\frac{3}{4} \times x-63$

Solving the above equation further we get,

$=>\frac{30}{100} \times x =\frac{3x}{4} -63\\\\=>\frac{30x}{100} =\frac{3x}{4} -63\\\\=>\frac{30x}{100} -\frac{3x}{4} =-63\\\\=>\frac{30x}{100} -\frac{3x\times25}{4\times25} =-63\\\\=>\frac{30x}{100} -\frac{75x}{100} =-63\\\\=>\frac{30x-75x}{100} =-63\\\\=>\frac{-45x}{100} =-63\\\\=>-45x=-63\times 100\\\\=>-45x=-6300\\\\=>x=\frac{-6300}{-45} \\\\=>x=140$

Hence, the number will be$140$.
