MOON : 3554:: STAY : 9015:: DREAM :

Solution

The logic followed here is: The word is coded as the unit digit of the place value of each letter as per the English alphabetical series. MOON = 3554 STAY = 9015  DREAM = 4518 Explanation: For each letter, convert it to its place value (A=1, B=2, ..., Z=26) and take the unit digit. - M = 13 -> 3 - O = 15 -> 5 - O = 15 -> 5 - N = 14 -> 4 Thus, MOON = 3554. S = 19 -> 9 - T = 20 -> 0 - A = 1 -> 1 - Y = 25 -> 5 Thus, STAY = 9015. D = 4 -> 4 - R = 18 -> 8 - E = 5 -> 5 - A = 1 -> 1 - M = 13 -> 3 Combining the units: DREAM = 48513.
