Question

After installation of solar panels, the electricity consumption is reduced by one-fourth of the total quantity.

The present electricity consumption is

• A. $\frac{9}{4}units$
• B. $\frac{7}{4}units$
• C. $\frac{6}{4}units$
• D. $\frac{8}{4}units$

Answer 1

The correct option is A $\frac{9}{4}units$


$\text{Total electricity consumption from the}$
$\text{line plot is:}\frac{1}{2}+1+2\times \frac{3}{2}+2+2\frac{1}{2}$

$=\frac{1}{2}+1+2\times \frac{3}{2}+2+2+\frac{1}{2}$

$=\frac{1}{2}+1+3+2+2+\frac{1}{2}$

$=\frac{1}{2}+\frac{1}{2}+8$

$=\frac{1+1}{2}+8$

$=\frac{2}{2}+8$

$=1+8$

$=9$

Present electricity consumption will be:

$=9\times \frac{1}{4}$

$=\frac{9}{4}units$

$\text{So, the present day consumption is}\frac{9}{4}units.$
