divide the clock face into three equal parts exactly.. Therefore the sum of the numbers in the 3 equal parts should be same
Answers
There are multiple ways of arranging numbers 1-12 into 3 sets such that sum of each set is equal. On could be : 1-6-7-12, 2-5-8-11, 3-4-9-10.
1) Sum of numbers from 1-12 is 78.
2) If we have to divide them into 3 sets with equal sum then sum of each set would be 78/3 = 26.
3) Hence, another possible combination would be 1-2-11-12, 3-4-9-10, 5-6-7-8
It is proved that the sum of the three sides are equal to each other, it is 26.
Given:
Divide the clock face into three equal parts exactly.
Therefore the sum of the numbers in the 3 equal parts should be same
Solution:
The clock has numbers from 1 to 12
It has to be divided into three parts such that their sum is equal.
They are,
i) 11 + 12 + 1 + 2
ii) 3 + 4 + 9 + 10
iii) 5 + 6 + 7 + 8
And it is proved that,
The sum of the three sides are equal to each other, it is 26.
11 + 12 + 1 + 2 = 3 + 4 + 9 + 10 = 5 + 6 + 7 + 8 = 26
