Question

Find the number whose 2 1/5% is 55.​

Answer 1

As per the given data, we have to find the value of the given expression.

We have to find the number whose$2\frac{1}{5} \%is 55$.

We are solving in the following way:

Let assume the number be'$x$'.

From the given statement, we can write:

$\Rightarrow x\times 2\frac{1}{5} \div 100=55$

Solving the above equation further we get,

$\Rightarrow x\times2\frac{1}{5} =55\times100\\\Rightarrow x\times2\frac{1}{5} = 5500\\\\\Rightarrow x\times\frac{5\times2+1}{5} =5500\\\\\Rightarrow x\times \frac{11}{5} =5500\\\\\Rightarrow \frac{11x}{5} =5500\\\\\Rightarrow 11x=5500\times\\\Rightarrow 11x=27500\\\\\Rightarrow x=\frac{27500}{11} \\\\\Rightarrow x=2500$

Hence, the number will be$2500$.

Answer 2

$the \: number \: = 2 \frac{1}{5} \% = 55$

a/q,

$\frac{ \frac{11}{5} }{100} = 55$

$= \frac{55 \times 5 \times 100}{11}$

$= 25 \times 100$

$= 2500$

hence, the number = 2500
