Question

Find 'x' if 40% of it is Rs. 2000?​

Answer 1

Answer:

Percentage solution with steps:

Step 1: Our output value is 2000.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$2000=100\%$.

Step 4: Similarly, $x=40\%$.

Step 5: This results in a pair of simple equations:

$2000=100\%(1)$.

$x=40\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{2000}{x}=\frac{100\%}{40\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{2000}=\frac{40}{100}$

$\Rightarrow x=800$

Therefore, $40\%$ of $2000$ is $800$
