50-18=32
18 + n*(-2) = 18 - 2n
23 + 2X = 5 2X = -18 X = -9
18 increased to 45 is a change of +150%
If the digit in the thousands place is increased by 1, the value of the number is increased by 1,000.
50-18=32
18 + n*(-2) = 18 - 2n
18
18 is increased to 45: 45-18=27 27/18 X100 1.5X100 150%
Every next number is increased by 5. The next number in the sequence is 23.
23 + 2X = 5 2X = -18 X = -9
So the original number was greater than 8...
18 increased to 45 is a change of +150%
Possibility of two digit no whose sum is 9 18,27,36,45,54,63,72,81 Now add 63 to each no mentioned above output is 81,90,99,108,117,126,135,144 See 18 and 81. If you reverse 18 . 81 will come which is the no increased by 63. 18 is
(7 * x) + 2 = 187x + 2 = 187x = 18 -27x = 16x = 16/7x = 2 2/7
Let X be one number and Y be the second number So X = 3Y and X + Y = 18 To solve, substitute the value of X from the first equation into the second equation. 3Y + Y = 18 4Y = 18 Y = 4.5 So X = 3*(4.5) = 13.5
92 + 18% = 108.56
