Question

Homi · Accepted Answer

Understand the Question

From the bar graph, determine the expenditure for Electricity and Education by reading the heights of their respective bars.
Divide the cost of education by $2$ to find half of its cost.
Compare the cost of electricity to half the cost of education to determine if they are equal.

Step 1 · Find Electricity Cost

From the bar graph, the bar for Electricity reaches the $400$ mark. Diagram 1

$\text{Cost of Electricity} = \text{₹ }400$

Step 2 · Find Education Cost

From the bar graph, the bar for Education reaches the $800$ mark. Diagram 2

$\text{Cost of Education} = \text{₹ }800$

Step 3 · Compare the Costs

Calculate half of the education cost

\begin{aligned} \text{Half of Education cost} &= \text{₹ }800 \div 2 \\[0.6em] &= \text{₹ }400 \end{aligned}

Since $\text{Cost of Electricity} = \text{Half of Education cost} = \text{₹ }400$ , the cost of electricity is one-half the cost of education.

Answer

Yes

Common Mistakes

Misreading Bar Values: Always check the vertical axis markings carefully to read the exact values (₹ $400$ for Electricity, ₹ $800$ for Education).
