Postal or Sorting Assistants Model Paper 8 With Solutions

(a) Difference in percentage of Aand B = (40-30) = 10%
Difference in marks = 50
Let maximum marks be x
10%of x= $50\mathit{x}=\frac{50\times 100}{10}=500$
A scored 30% of 500 means 150 marks minimum marks
required to pass = 150 + 15 = 165
Pass %= $\frac{165}{500}\times 100=33\%$
