In which of the following States the yield of forest wealth per acre is highest?

Answer: (b) Madhya Pradesh

The key picks Madhya Pradesh.

The idea

Yield per acre measures output from a unit of land, whereas total forest wealth depends on both area and yield. The output might mean timber volume or its value, which are different measures. A historical ranking needs the original definition and data year; forest area alone cannot establish it.

Why the others are wrong

(c) Kerala’s forests are rich per hectare — a strong alternative.

The trap

MP has the largest forest AREA; yield per acre is a different measure.

Also know

An acre is about 0.405 hectare. Tropical evergreen forests, moist deciduous forests and dry deciduous forests differ in species and growth conditions. Standing timber stock, yearly growth and commercial harvest are separate indicators, so none should silently replace the others.
