Answer the following questions by selecting the correct/most appropriate option.

A vegetable seller was selling spinach for ₹60 per kg. Sonu purchased 350g of spinach for which the vegetable seller took ₹21 (₹6+₹6+₹6+₹3) from Sonu. Which of the following statements is/are true regarding the mathematical skills used by the vegetable seller?
A. This mathematical skill is ambiguous.
B. This skill is not useful to solve mathematical problems in class.
C. Such skills help in developing alternate strategies for solving mathematical problems.
Choose the correct option:

Correct option is A

A. This mathematical skill is ambiguous: The pricing strategy employed by the vegetable seller can be seen as somewhat ambiguous. Instead of charging a straightforward ₹60 per kg, the seller appears to have divided the price into smaller units (₹6 and ₹3) for ease of calculation. This could be considered ambiguous because it departs from a standard pricing method.
B. This skill is not useful to solve mathematical problems in class: On the contrary, this skill can be useful in a classroom setting. It demonstrates an alternative strategy for calculating prices and could be a valuable example for teaching students to think creatively and develop alternate problem-solving methods.
C. Such skills help in developing alternate strategies for solving mathematical problems: This statement is true. The vegetable seller's approach showcases an alternative strategy for calculating the price of vegetables. Encouraging students to explore different problem-solving methods is a valuable aspect of mathematical education.
So, option (a) is the correct choice as it acknowledges the ambiguity of the seller's method while also recognizing the usefulness of such skills in developing alternate problem-solving strategies.
