Max is thinking of an odd number between 42 and 64 The between the the digits is same as the digit in the ones place What is Max's number?
63
C program to find the largest digit of a number?
#include<stdio.h> #include<conio.h> main() { int n,max=0,rem; printf("\n enter a number"); scanf("%d",&n); while(n!=0) { rem=n%10; n=n/10; if(rem>max) { max=rem: }} printf("\n the largest digit is: %d",max); getch(); }
Find large number in the given two numbers?
int max = a>b?a:b; // set max to the larger of a and b
When was the number plane invented?
it was invented in 1950 when a Australian man Max Carter invented it because he wanted to make sense with direct numbers
How do you solve Max is thinking of an odd number between 42 and 64. The difference between the digits is the same as the digit in the ones place. What is Max's number?
Leaving aside the brute force method of trying all the number, The following is one way of reducing the number of possible solutions. You can elect, at any stage, to quit this process and try out each of the remaining possibilities. Max's number is odd. so it must be one of 43, 45, 47, 49, 51, 53, 57, 59, 61, 63. The difference between the digits is the same as the units digit which is odd. If the tens digit is 5, then the difference between 5 and the odd units digit would be even. That means the tens digit cannot be 5. Which leaves the following as possible solutions: 43, 45, 47, 49, 61, 63. Now, the tens digit is 4 or 6. The units digit must be between 1 and 9 (it is odd). so the difference between the tens and units digit must be 5 or fewer ie not 7 or 9. Then, since the difference is the same as the units digit, the units digit cannot be 7 or 9. So that leaves 43, 45, 61, 63. Now 43 an 45 both result in a difference of 1, not the units digit so neither can be a solution. That leaves 61 and 63. 61 has a digital difference of 5, not the units vaue which is 1. So 1 is not a possible answer and that leaves only 63. 6-3 = 3 so the difference is the same as the units digit. And that, my friend, is the answer - at long last!
