Present Population given Future Population at End of n Decades by Arithmetic Increase Method Solution

Follow our step by step solution on how to calculate Present Population given Future Population at End of n Decades by Arithmetic Increase Method?

FIRST Step Consider the formula

P o = P n - n \cdot X̄

Next Step Substitute values of Variables

∴

P o = 350000 - 2 \cdot 37500

Next Step Prepare to Evaluate

∴

P o = 350000 - 2 \cdot 37500

LAST Step Evaluate

∴

P o = 275000
