SCORPION-xisa [38]

\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}

Let the number of girls = x

Then, According to the question,

number of the boys = 9 + 3x

Total students in class = 60, so

9  + 3x + x = 60 \\  =  > 9 + 4x = 60 \\  =  > 4x = 60 - 9 \\  =  > 4x = 51 \\  =  > x = 51 \div 4 \\  =  > x = 12.75

On rounding off

How does adding the log together automatically mean that it is a factorial?
andreyandreev [35.5K]

Answer: The answer is given below.

Step-by-step explanation:  We are given an equality involving logarithm and we are to show the implication of L.H.S. to R.H.S.

We will be using the following two properties of logarithm:

(i)~\log_ba=\dfrac{1}{\log_ab},\\\\\\(ii)~log_ab+\log_ac=\log_a(bc).

The proof is as follows:

L.H.S.\\\\\\=\dfrac{1}{\log_2N}+\dfrac{1}{\log_3N}+\dfrac{1}{\log_4N}+\cdots+\dfrac{1}{\log_{100}N}\\\\\\=\log_N2+\logN3+\log_N4+\cdots+\log_N100\\\\=\log_N\{2.3.4...100\}\\\\=\log_N\{1.2.3.4...100\}\\\\=\log_N{100!}\\\\=\dfrac{1}{\log_{100!}N}\\\\=R.H.S.

Hence proved.
