Question 55
The full marks for a paper is 300. The break-up of the marks into theory (X), practical (Y) and project (Z), which are the three components of evaluation is 6 : 5 : 4. In order to pass one has to score at least 40%, 50% and 50% respectively in X, Y, Z and 60% in aggregate. The marks scored by four students A, B, C and D are shown in the given Bar Graph.
How much percentage marks more than B has C scored in practical ?
Solution
Full marks of practical $$= \frac{5}{15}\times300=100$$
Percentage of B $$=\frac{50}{100}\times100$$=50%
Percentage of C $$=\frac{80}{100}\times100$$=80%
Required percentage $$= 80 - 50 = 30$$
