2 + 47 = 49, 2 x47 = 94 so the digits of the answer are the same but in reverse when you add or multiply 2 and 47. Can you find other pairs which have answers with digits reversed when added and multiplied?
Answer: 3, 24 3 + 24 = 27 3 * 24 = 72 so the digits of the answer are the same but in reverse when you add or multiply 3 and 24
A number when divided by 48 gives 47 as remainder and x as quotient, the same number when divided by 49 gives 8 as remainder and y as quotient. What is the minimum possible value of x?
Find a two digit number, so that when the digits are added together the answer is one third of the answer when the 2 digits are multiplied together.
What is the number if it divides exactly by 13 and when you write its digits in reverse order you make a square number. (You get a square number when you multiply a number by itself - 64 is square because it is 8 times 8)
When a two digit number is multiplied by sum of its digits, the product is 715 but when the reverse of a two digit number is multiplied by sum of its digits the product obtained is 99 less. What is the sum of the digits of a number?
