SOLUTION TO LAST MONTH'S QUIZ

  1.  9
  2.  62
  3.  66

Notes. If there are M men and W women, then the number of children = 100 - M - W. So 6000 M + 4000 W + 1000(100 - M - W) = 242,000 Hence 5 M + 3 W = 142 By trial and error, the following are the only possible solutions: Men Women Children 2 44 54 5 39 56 8 34 58 11 29 60 14 24 62 17 19 64 20 14 66 23 9 68 26 4 70

THIS MONTH'S QUIZ

Notice that 35 X 41 = 1435.
The product contains the same four digits as the multiplier and the multiplicand.

Find three other pairs of two-digit numbers (neither of which contains a zero) with this same property.
