Question

From the bar graph given below, in which of the two months the difference between the consumption of electricity is 30 megaWatts?
​

Answer 1

Answer:

2. February and April

Explanation:

In the given bar graph,

There is collection of data of electricity consumption from January to May (in Mega Watt)

The data is as follows:

• January = 40 µW
• February = 30 µW
• March = 50 µW
• April = 60 µW
• May = 40 µW

Clearly, from the given data we can observe that the consumption between February and April is 30 µW.

Hence, the consumption of electricity between February and April is 30 Mega watts.

${\textsf{\textbf{2. February and April is the correct option }}}$

Mega watts sign is: µW

Answer 2

Given :-

A bar graph of consumption in different months

To Find :-

which of the two months is the difference between the consumption of electricity is 30 megaWatts?

Solution :-

From the given graph we get

The consumption of electricity are :-

$\left\{\begin{array}{ccc}\bf January=40\;MWe\\\bf February=30\;MWe\\\bf March=50\;MWe\\\bf April=60\;MWe\\\bf May=40\;MWe\end{array}\right\}$

Coming to the options

1. February and March

50 - 30

20

Which is incorrect

2. February and April

60 - 30

30

Which is correct

3. April and May

60 - 40

20

Which is incorrect

4. March and May

50 - 40

10

Since

The difference of consumption of electricity in February and April is 30. So, Option B is correct
