[amp_mcq option1=”30.5″ option2=”31.5″ option3=”31″ option4=”30″ correct=”option1″]<\/p>\n

The correct answer is (a) 30.5.<\/p>\n

The total marks of the 11 students is 11 x 31 = 341.
\nThe total marks of the first 6 students is 6 x 31.5 = 189.
\nThe total marks of the last 6 students is 6 x 30 = 180.
\nThe mark of the sixth student is 189 + 30.5 = 219.5.
\nSince the mark of the sixth student cannot be a fraction, the mark of the sixth student is 30.5.<\/p>\n

Option (b) is incorrect because the mark of the sixth student cannot be 31.5.
\nOption (c) is incorrect because the mark of the sixth student cannot be 31.0.
\nOption (d) is incorrect because the mark of the sixth student cannot be 30.0.<\/p>\n","protected":false},"excerpt":{"rendered":"
