(c) 10,456
(d) none of the options
Answer: (d) none of the options
Arranging the digits 0, 1, 4, 5, 6 in ascending order gives 01456, but a number cannot start with 0. Placing the next smallest non-zero digit first gives 10,456. Since option (c) is 10,456, wait, let us check: digits given are 4, 5, 1, 0, 6. The sorted non-zero start is 1, followed by 0, 4, 5, 6 which makes 10,456. Option (c) is indeed 10,456. Therefore, the correct option listed is (c).
In simple words: Arrange the digits from smallest to largest, but make sure the first digit is not zero.

Exam Tip: When 0 is among the digits, put the second smallest digit in the first place, then put 0 in the second place.

Answer:
Cake given to Simran = \(\frac{5}{8}\)
Cake given to Mehar = \(\frac{3}{8}\)
Comparing the numerators since denominators are equal: \(5 > 3\), so Simran has eaten more cake.
Difference = \(\frac{5}{8} - \frac{3}{8} = \frac{5 - 3}{8} = \frac{2}{8} = \frac{1}{4}\) of the cake.
In simple words: Simran ate more cake by \(\frac{1}{4}\) of the cake.

Question iv. Rohan completed his 25 days craft classes on 19th November. When did he join the craft classes?
Answer:
Total duration of classes = 25 days.
Completion date = 19th November.
Including 19th November as the last day, counting backwards:
Days in November included = 19 days.
Remaining days to count in October = \(25 - 19 = 6\) days.
October has 31 days. Counting backwards 6 days from October 31st gives October 26th.
Therefore, Rohan joined on 26th October.
In simple words: Count back 25 days from November 19th to find the starting date of October 26th.

Exam Tip: Be careful with month boundaries and whether start or end dates are inclusive.
