Q1Assertion: In 2 red beads and 3 blue beads, the total beads are 5. Reason: A ratio 2:3 names two parts, not only the second number.
The reason explains the assertion. When Meena reads 2:3, she should see 2 red parts and 3 blue parts. The total is therefore 5 parts or 5 beads in this concrete example.
Q2A teacher writes: known fact, value of one, required value. Which problem best fits this board layout?
The board layout fits unitary method. Asha would divide 48 by 6 to get one notebook at 8 rupees, then multiply 8 by 9 to get 72 rupees for 9 notebooks.
Q3Which pair of ratios is not a proportion?
To check a proportion, both terms of a ratio must change by the same multiplier or reduce to the same form. In 3:4 and 9:16, the multipliers are different, which is the unchecked-ratio-equality trap.
Q4Which pair of ratios forms a proportion?
A proportion states that two ratios are equal. The ratios 2:3 and 4:6 match because both terms of 2:3 have been multiplied by 2; the other pairs change only one side of the comparison or compare different parts.
Q5Three notebooks cost ₹24. Using the unitary method, what is the cost of 5 notebooks?
The unitary method first finds the value of one unit: ₹24 divided by 3 is ₹8. Then ₹8 multiplied by 5 gives ₹40; the other choices confuse one notebook, addition, or direct multiplication by 5.
