Assume sum of digits as x+y. It is given x+y=10. Assume those two digit no as 10x+y reverse of it is 10y+x It is given if you reverse it new no will be 54 less than original no So 10y+x=10x+y-54 -9x+9y=-54 -9(x-y)=-54 x-y=6 Equate x+y and x-y x+y-10=x-y-6 x+y-10-x+y+6=0 2y-4=0 y=2 substitute this in x+y =10 x+2=10 x=8 Substitute this x and y in two digit no we assumed that is 10x+y 10*8+2= 82 is original no Reverse of it 28 Ans is 82
If: 4x-6 = 54 then the value of x works out as 15
To find this out, divide the larger number by the smaller number.To find this out, divide the larger number by the smaller number.To find this out, divide the larger number by the smaller number.To find this out, divide the larger number by the smaller number.
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
Nope, wrong, wrong, wrong, its obviously 54 (less than 57) and as high as can be, its not 8, not 12 ITS 54!!! (proof): multiples of six: 6, 12, 18, 24, 30, 36, 42, 48 and 54. (54 + 6 IS MORE THAN 57 SO ITS 54) don't listen to them, its SOOO 54 =_=
It is: 54 because .1 is less than .5
The number is 54. It is greater than 36 and less than 70. One of its factors is 9 and it is an even number.
Add up its proper factors. If that sum is less than 54, it's deficient.
0.035 is less than one and cannot be expressed as a whole number.
y=88 88/2=44 44+10=54
7 (x+1)/72 = (x-1)/54 x+1 = (72x-72)54 54x+54 = 72x-72 54x-72x = -72-54 -18x = -126 x = 7
54 - 8 = 46.
Possibility of two digit no whose sum is 9 18,27,36,45,54,63,72,81 Subract 9 with each no mentioned above output is 9,18,27,36,45,54,63,72 See after 4th comma 54 and 45. Reverse 54=45. now 45 is 9 less than 54. So the original no is 54
54
54
18. 54
54 over 10 renamed as a mixed number = 52/5
