Question : 60 of 150

Marks: +1, -0

In a class text, to the question, find out 23% of 200, two students answered in the following ways:
Student A: 23% of 200 = 23% of (100 + 100) = 23 + 23 = (20 + 20) + (3 + 3) = 46
Student B: 23% of 200 = 200 ×

\;{23}/{100}

= 2 × 23 = 46
Which of the following statements is the most appropriate in the given context?

Since student B has used the standard algorithm, teacher gives full marks to student B and zero to student A
Teacher gives full marks to both the students as they have attempted the question using their own algorithms. Both formal and informal algorithms are integral to solving problems in mathematics.
Teacher gives zero marks to student A and directs him to redo the question using the algorithm taught in the Class
Teacher accepts both the responses but directed student A to refrain from using informal algorithm
