● NUMBERMANIA: Calculate the number 4293 using numbers [9, 7, 1, 9, 24, 570] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. ● The aim is to place the some numbers from the list (6, 11, 16, 18, 19, 31, 35, 36, 40, 41, 45, 95) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B*C. ● If b94ab + 3a66c = 6acc3 find number abc. Multiple solutions may exist. ● The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot. ● NUMBERMANIA: Calculate the number 4438 using numbers [8, 6, 6, 9, 24, 302] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. ● If c40b1 + a313b = 15b208 find number abc.

I will grant you three wishes . . . maybe!?

An older couple were walking on a beach when the husband tripped over a bottle and a genie came out.

“You can each have one wish,” said the genie. The wife made her wish first “I would like to travel around the world, with my husband,”.

Suddenly there appeared in her hand two tickets for travel around the world.

Now it was the husbands turn, “Well” said the husband, with a naughty look on his face “I wish I can have a younger companion,” . The words were barely out of his mouth when poof,

he aged 20 years!

Chernobyl fall-out over UK

In 1986, because of fallout from the Chernobyl nuclear plant explosion in Russia on 26 Apr 1986, the slaughter and movement of lambs in parts of Cumbria, Scotland, was temporarily banned.Fallout in the UK from the Chernobyl accident was greatest where the passage of the cloud coincided with heavy rainfall in north Wales, Cumbria, parts of Scotland and northern Ireland. Caesium-137 activity concentrations in vegetation at one site in upland west Cumbria increased from 40 to 10,000 Bq kg–1 dry weight. Studies after the Chernobyl accident have shown that the transfer of radionuclides to sheep and goat products is greater than to cattle. Restrictions are imposed if any individual sheep in a flock exceeds the 1,000 Bq kg-1 (fresh weight) limit at which meat cannot enter the foodchain.[Image: Upland sheep in the area of Cumbria where movement and slaughter were still restricted 10 years after the Chernobyl accident.]
