multiplier reasoning MCQ Questions for Class 12

Simple Explanation

Population \(P = D \times A\) है। Density multiplier 0.8 और area multiplier 1.25 है। इसलिए population multiplier \(0.8 \times 1.25 = 1.0\) है। अर्थात population unchanged रही। इसलिए पहला विकल्प सही है। यह question दिखाता है कि density decline जरूरी नहीं कि population decline को दर्शाए; area expansion भी density कम कर सकती है। / Population is \(P = D \times A\). The density multiplier is 0.8 and the area multiplier is 1.25. Their product is \(0.8 \times 1.25 = 1.0\), so population remained unchanged. Therefore, the first option is correct. This question shows that a decline in density does not necessarily mean population decline; expansion of area can also lower density.
