Q:

Can you Solve the Problem ?

SOLVE1500443612.jpg image

Answer

Let the two digits be x & y


From given data in the question, we get


x + y = 3(x - y)


x + y = 3x - 3y


=> 2x = 4y


x/y = 2/1


For having the 2:1, numbers satisfying are


12, 21, 24, 42, 36, 63, 48, 84


From this 36 is eleminated because it is a perfect square and no others are prime or perfect squares.


Hence, there exists 7 such 2-digit numbers => 12, 21, 24, 42, 63, 48, 84.

Three years in the making, it's estimated to have cost the Chinese government around 1 billion yuan (or US$144 million).The bridge is going to cut travel times between Liupanshui in the Guizhou province and Xuanwei in the Yunnan province to two hours instead of the current five – as long as you don't mind the heights.The bridge crosses the the Nizhu river, and to give you some idea of the size of the drop down to the water below, it's almost 2 Eiffel Towers or one-and-a-half Empire State Buildings.
