Correct Answer - Option 3 : 75% decrease
Given-
Total amount divided = 1875.49
Incorrect ratio of distribution = 1 : 2 : 4
Correct ratio of distribution = 4 : 2 : 1
Calculation-
Share of Ram if the amount was distributed in the ratio of 4 : 2 : 1 = 4/7
Share of Ram if the amount was distributed in the ratio of 1 : 2 : 4 = 1/7
Decrease in his share = 4/7 - 1/7 = 3/7
%Decrease in his share = (3/7)/(4/7) × 100
⇒ 75%
∴ Ram's share decreased by 75% due to this incorrect distribution.
