Answer» Answer: answer=74 Step-by-step explanation: What an odd question… well, first we should figure out the PAIRS of single digit numbers that ADD up to 11. Those are 2+9, 3+8, 4+7, 5+6 and their inverted pairs 6+5, 7+4, 8+3, and 9+2. Now, of those, we need to find a number that is 27 greater than when it is inverted. 92 – 29 = 63 83 – 38 = 45 74 – 47 = 27 65 – 56 = 9 Now, the problem asks for the ONE that is greater of 74 and 47, which is 74. The answer is 74. I hope helps to you |
