and
x - y = 2 . . . . . . (B)
(A) + (B) gives 2x = 56 so that x = 56/2 = 28
and then, by (B), 28 - y = 2 so that y = 26.
So the two numbers are 28 and 26
To do this, you would divide 54 by two, in order to get 27 next, you would subtract by the difference in order to get the first number: 27-1=26 secondly, you would add one to half of the original number: 27+1=28 Lastly, check to see if the answer is right: 28+26=54 that is your answer
Possibility of two digit no whose sum is 10 19,28,37,46,55,64,73,82,91 Now add 54 to each no mentioned above 73,82,91,100,109,118,127,136,145 See after 1st comma 28 and 82 Reverse of 28 is 82. That no 82 is 54 more than the no 28. So 28 is the original
There is a very easy way to do this type of thing:Subtract the difference, then half the answer, this gives the smaller number. Add back the difference to get the larger number.In this case 90 - 18 = 72; 72/2 = 36 then 36 + 18 = 54.
Possibility of two digit no whose sum is 9 18,27,36,45,54,63,72,81 Now add 9 to each no mentioned above 27,36,45,54,63,72,81,90 See after 3rd comma 45 and 54. reverse of 45 is 54. 54 is 9 more than 45. So 45 is the original
222. To get from 5 to 12, we add 7. To get from 12 to 26, we add 14. To get from 26 to 54, we add 28. To get from 54 to 110, we add 56. The number added is doubling each time. So next time we need to add 112 (56*2), so the next number in the sequence is 222.
27 and 81

The numbers are 133 and 54
Possibility of two digit no whose sum is 10 19,28,37,46,55,64,73,82,91 Now add 54 to each no mentioned above 73,82,91,100,109,118,127,136,145 See after 1st comma 28 and 82 Reverse of 28 is 82. That no 82 is 54 more than the no 28. So 28 is the original
(18 + 36) + (45 - 27) = 54 + 18 = 72
Take the average of the two numbers. That is, add the two together, and divide the result by 2.then the answer will be 54.
(54 - 18) ÷ 6 = 6 :)
x - 12 = 54 Therefore, x = 54 + 12 = 66
There is a very easy way to do this type of thing:Subtract the difference, then half the answer, this gives the smaller number. Add back the difference to get the larger number.In this case 90 - 18 = 72; 72/2 = 36 then 36 + 18 = 54.
Two digit no possibility whose sum is 12 = 39,48,57,66,75,84,93 See the difference of above no with 54 1.39-54=-15 2.48-54=-6 3.57-54=3 4.66-54=12 5.75-54=21 6.84-54=30 7.93-54=39 The last no 7 mentioned shows 93 is the ans because if you reverse it 39 will come it 54 less than 93. And=93
27*2 = 54
9 and 6 but subtract not add
