Pedometer perceive nines as tens so the real value of his pedometer's 5780 is 5x9x9x9 + 7x9x9 + 8x9 + 0 .
Calendar counts 9 instead of seven so it gets 7 times 5780 and divides this by 9.
There is 10 possible values for A. Take A=9 and evaluate AxB.
If the result is not proper, make A=8 and subtract 40 from the previous AxB product.
1000 x 46438754 - 111 x 46438754 may be easier to calculate !
c: 11088+11088+110880=133056 .
They should be 125 and 500 .
Find first how many groups of sheep he has .
If he has 7 groups and the sack is 39 kg. the conditions are satisfied .
196 drops and the minimals of A and B are 10 and 12. .
nine shares will be made.
7 x 128 = 896 .
You can easily guess that the average should be about 17-18 by having a look at samples.
1, 6, 6 and 2, 2, 9 are such having a sum of 13 and 13 will be used twice in forming the total.
First find all 3 numbers having a product of 36.
Then find the sums of these three numbers.
Then find the grand sum of cases.
Divide this grand sum by the number of the cases.
The question refers to Erdal's friends; take care .
1. Find first monthly yield by multiplying the given averages by 30 for each month.
2. For yearly yield find the sum of numbers from 1 to 25 and subtract the sum of from 1 to 16 .
Remember that the sum of first 5 naturals gives 15 .
The method is called cage (lattice) method and may be useful depending on the case.
172x896 = 154112.
The summation upper left is vertical.
This is a case where the cage method is of some use. The tarnsverse yellow region has a sum A+B+2 = 9 ...
