39. 2. The average of three numbers is 44. The first is 6 less
than the average, the second is 5 less than the average and
the third is 11 more than the average. What are the three
numbers?
Average of 3 numbers = 44. 1st number = 44 โ 6 = 38, the second number 44 โ 5 = 39
and the third number = 44 + 11 = 55.

41. 4. The ones digit of a two-digit number is half of the tens digit
and their sum is 12. If the digits are interchanged the resulting
number is 36 less than the original number. Find the number.
Let a = tens digit and b = the ones digit. Since b= ยฝ of a, then a + ยฝ a = 12 , 3a = 24
therefore a= 8 and b = ยฝ of 8 = 4. 84 โ 48 = 36 . The number is 84.
42. 5. Find a 4-digit number in which the second digit is half the first;
the third digit is the sum of the first two digits and the fourth digit
is the product of the first two digits. Can you find more than one
number?
Two possible answers are: 2132 and 4268.
