Question 21


The given table represents the marks obtained by four students W, X, Y and Z in four subjects P, C, B and M, with the maximum marks in each subject being 100.

Based on the given data, W’s marks percentage in P, C and B combined is:

Solution

Marks obtained in P = 70
Marks obtained in C = 90
Marks obtained in B = 50
Total marks obtained in P, C and B together = 70+90+50 = 210
Maximum marks of P, C and B together = 100+100+100 = 300
Therefore, Percentage of marks obtained in P, C and B together = $$\dfrac{210}{300}\times100 = 70$$%
