Direction : Study the following table and answer the questions that follow : Electricity consumption (in MWh) in three quarters (Q1, Q2 and Q3) by five industrial zones (U, W, X, Y and Z)Industrial Zone Electricity Consumption (in MWh) Total Q1 Q2 Q3 U 120 150 180 450 W 180 210 240 630 X 160 180 220 560 Y 240 240 300 780 Z 200 220 260 680 Total 900 1000 1200 3100
If 40 MWh of Zone Y’s Q3 electricity consumption is reassigned to Zone X, while the total Q3 consumption remains unchanged, what would be the ratio of the revised Q3 consumption of Zone X to the revised Q3 consumption of Zone Y ?
1 : 1
Reassigning consumption moves the same amount from one zone to another, so one zone falls by 40 MWh and the other rises by 40 MWh while the Q3 total stays 1200 MWh.
Step 1 — From the table, Q3 consumption is 220 MWh for Zone X and 300 MWh for Zone Y.
Step 2 — Revised Zone X = \(220 + 40 = 260\) MWh; revised Zone Y = \(300 - 40 = 260\) MWh.
Step 3 — Ratio X : Y = \(\frac{260}{260} = 1\), i.e. 1 : 1.
3 : 4 is close to the original ratio before the transfer (220 : 300 = 11 : 15), and 2 : 3 or 2 : 1 would need unequal revised values, so they do not fit.
1 : 1 option is correct.
