Number Play Class 6 MCQ Questions with Answers
In a height-comparison game, a child standing between two other children says “2”. What does this indicate?
The number tells how many immediate neighbours are taller. A value of 2 means both adjacent children are taller.
Which statement best describes a supercell in the Number Play chapter?
A supercell is identified by comparing its value with its immediate neighbouring cells. It must be greater than each of them.
What is the digit sum of 731?
Add the digits: 7 + 3 + 1 = 11.
Which of the following numbers is a palindrome?
3443 reads the same from left to right and from right to left, so it is a palindrome.
What is Kaprekar’s constant for the standard 4-digit Kaprekar routine?
For a 4-digit number having at least two different digits, repeatedly arranging the digits in descending and ascending order and subtracting leads to 6174.
Using the Collatz rule, what comes immediately after 13?
13 is odd, so apply 3n + 1: 3 × 13 + 1 = 40.
What is the smallest 5-digit number in which every digit is odd?
The smallest odd digit is 1. Using 1 in all five places gives the smallest possible 5-digit number with only odd digits: 11111.
Which number is palindromic?
Reversing 123321 gives 123321 again, so it is a palindrome.
How many times does the digit 7 appear when writing all whole numbers from 1 to 100?
There are 10 occurrences in the ones place (7, 17, …, 97) and 10 in the tens place (70–79). The two 7s in 77 are correctly counted separately, giving 20 occurrences.
On a digital clock written in HH:MM form, what is the next palindromic time after 10:01?
A palindromic HH:MM time reads the same when the four digits are reversed. After 10:01, the next such time is 11:11.
Which 4-digit numbers reach 6174 under the standard Kaprekar routine?
The routine works for 4-digit numbers having at least two distinct digits. When a result has fewer than four digits, leading zeros are retained for the next step.
In a table containing distinct numbers, what must be true about the largest number in the table?
Because the numbers are distinct, the largest number is greater than every cell next to it. Therefore it satisfies the supercell condition.
Which number has digit sum 14?
6 + 8 = 14. The other digit sums are 9, 10 and 8 respectively.
What operation is applied to an odd number in a Collatz sequence?
For an odd number n, the Collatz rule gives the next term as 3n + 1.
Using the digits 1, 2, 3 and 4 exactly once, what is the difference between the largest and smallest 4-digit numbers that can be formed?
Largest = 4321 and smallest = 1234. Therefore 4321 − 1234 = 3087.
What is the sum of the smallest and largest 5-digit palindromes?
The smallest 5-digit palindrome is 10001 and the largest is 99999. Their sum is 110000.
In the game of 21, players add 1, 2 or 3 to the running total and the first to reach 21 wins. Which sequence is the winning set of target numbers for Player 1 when Player 1 starts correctly?
The target numbers are 1, 5, 9, 13, 17 and 21. After the opponent adds 1, 2 or 3, Player 1 adds the complementary amount so the two moves together advance by 4.
A person breathes about 16 times per minute. Which range is the best estimate for the number of breaths in one day?
16 × 60 × 24 = 23,040, which lies in the range 15,000–25,000.
Consider these four situations: (i) 5-digit + 5-digit = 6-digit, (ii) 5-digit − 5-digit = 3-digit, (iii) 5-digit + 3-digit = 6-digit, and (iv) 5-digit − 2-digit = 5-digit. Which statement is correct?
Examples prove each case: 50000 + 50000 = 100000; 10500 − 10000 = 500; 99999 + 999 = 100998; and 20000 − 50 = 19950.
Which rule correctly describes the Collatz process?
If the current number is even, divide it by 2. If it is odd, multiply it by 3 and add 1. The claim that every positive starting number eventually reaches 1 is still a conjecture, not a proved theorem.
Important Number Play Topics to Revise
The Collatz process can be tested for many starting values, but the statement that every positive starting number eventually reaches 1 is still unproved.
