Question 17 : In an examination, the score of A was 10% less than that of B, the score of B was 25% more than that of C, and the score of C was 20% less than that of D. If A scored 72, then the score of D was [TITA]
From the data,
A scored 72
A's score was 10% less than B
So, Score of B = 80
We know that B was 25% more than C
So, C x = 80
C = 64
Now, we know that D scored 20% less than D
So, C = x D
64 = x D
D = 80 marks
The question is "In an examination, the score of A was 10% less than that of B, the score of B was 25% more than that of C, and the score of C was 20% less than that of D. If A scored 72, then the score of D was [TITA]"
