by 30%?​

Answer 1

Step-by-step explanation:

$\huge\underline\blue{Answer}$

$let \\ the \: number = x \\ according \: to \: the \: question \\ x - 30\% = 56 \\ = > x - \frac{30}{100} = 56 \\ = > x = 56 + \frac{30}{100} \\ = \frac{5600 + 36}{100} \\ = \frac{5636}{100} \\ = 56.36$

the number is 56.36

Let

the new number is y

according to the question

56.36× $\binom{30}{100}$

=14.9× $\binom{30}{25}$

${14.9} \times{{\binom{6}{5}}}$

=17.88

hence y=56.36+17.88

=>y=74.24

thus the answer is 74.24
