In a class text, to the question, find out 23% of 200, two students answered in following ways: Student A: 23% of 200 = 23% of (100 + 100) = 23 + 23 = (20 + 20) + (3 + 3) = 46 Student B: 23% of 200 = 200 × \(\frac{23}{100}\) = 2 × 23 = 46 Which of the following statements is the most appropriate in the given context 1. Since student B has used the standard algorithm, teacher gives full marks to student B and zero to student A 2. 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. 3. Teacher gives zero marks to student A and directs him to redo the question using the algorithm taught in the Class 4. Teacher accepts both the responses but directed student A to refrain from using informal algorithm ?

Option 2 : 2

Mathematics is a science that deals with logical reasoning, quantitative calculation, practices of counting describing shapes, abstraction of subject matter, etc. Mathematics plays a vital role in daily life.

In this question, both the students have solved the problems according to their understanding of algorithms which is correct, so the teacher assigns full marks to both the students.
