$$\begin{array}{cc}Item& Priceinrupeesperkg\\ Onions& 10\\ Carrots& 16\end{array}$$

• A. $\frac{1}{4}$ kg carrots
• B. $\frac{1}{2}$ kg onions
• C. Both cost the same
• D. None of the above

Answer 1

The correct option is B $\frac{1}{2}$ kg onions

Cost of 1 kg of onion = ₹ 10
Cost of $\frac{1}{2}$ kg of onion = 10 ÷ 2 = ₹ 5
Cost of 1 kg of carrot = ₹ 16
Cost of $\frac{1}{4}$ kg of carrot = 16÷4 = ₹ 4
₹ 5 is greater than ₹ 4. Therefore, $\frac{1}{2}$ kg of onion costs more than $\frac{1}{4}$ kg carrot.
