An examination was conducted for 1200 marks. A scored 25% more than B and B scored 20% more than C. C scored 20% less than D. If A secured 720 marks, what percentage of full marks did D get?
Let the mark scored by D = 100
Hence, marks scored by C =80, B = 96, A = 120
If 120 = 720
then 100 = 600
Percentage score of D = 600/1200 × 100 = 50%
