The number within the four sectors of the outer circle is equal to the sum of the three numbers in its sector. The numbers in the individual circles can only be 0 to 8 and each number can be used only once. The total sum for all the numbers in the outer circle is equal to 36. Two numbers have been provided to get you started. Find the remaining six numbers.
Starting from number 5 in anti clockwise direction - 5,1,3,6,7,4,8,2
Below is the description - First and Second digits are common digits - 5,3,1 = 9 3,7,6 =16 8,7,4 =19 8,5,2 =15
If we have four positive numbers a, b, c and d, there are six ways to multiply the pairs i.e. a*b, a*c, a*d, b*d and c*d. If we tell you the result of five of them without telling you which one is the product of which pair as 2, 3, 4, 5 and 6.
What is the remaining product?
You are given with six numbers – 1, 2, 3, 4, 5 and 6. You can arrange them in any order and you can use all four mathematics expressions i.e. add, subtract, multiply and divide and also parenthesis. The result must be 278.
There are three other rules 1) You can only use a number once. 2) It is not compulsory to use all the six numbers. 3) You can’t join numbers i.e. you can’t use 1, 2 and 3 as 123.
The average of 14 number is 47. The average of the last five numbers is 50 and that of first six numbers is 44. The ninth number is 3 less than the seventh number but 6 more than the eighth number. What is the average of eighth and ninth number?
