From the bartender’s corner – Roq Candy
Love the color of the drink. I took a few pictures with my normal black background and then out in the yard. The color comes from the light blue color of Hypnotiq and the pale yellow color of pineapple juice. For the alcohol, you put in vodka. I am not the biggest fan of pineapple juice but the drink was good for a hot day after a long motorbike ride.

The legs are getting weary
54 years of standing up and 15 years of pounding the trails – the muscles are getting a bit stiff. The left hip is the main challenge.
Usually yoga, stretches and hot tub gives a lot of relief – but did I mention that I have lost some of the discipline in that? Need to get back on the horse again… of course, the left hip permitting 🙂

A puzzle from my nephews in Kolkata
Reeling under the lack of power, water supply and all that the devastating cyclone Amphan left behind, apparently my nephews hunkered down and started doing puzzles. They could not wait for power to come back – so that they could recharge their phones and send me this problem thru Whatsapp.
Good problem. About 2 years back, I had posted a similar version of the problem.

This week’s puzzle
This week is another area problem. Take a rectangle ABCD (as shown here). Draw two lines from the adjacent vertices A and D to two random points E and F on the opposite side such that they intersect within the rectangle. See picture below. Nothing is drawn to scale. The area of the two triangles are 4 and 16. One of the quadrilaterals has an area of 10. What is the area of the other quadrilateral?
Again, this is geometry from elementary school with a twist to it.
Note that the original version of the problem that I had posted had the quadrilateral area as 1 instead of 10. Harmindar Matharu successfully proved that such a diagram is not possible. I should have been more careful while picking some values for those areas…

From the bartenders’s corner – Blue Grass Cocktail
I am not sure of the origin of the name. One can safely guess the Kentucky connection of Bourbon whiskey has to do at least something with it. I remember flying into Lexington, KY for work in my previous life and the airport was called Blue Glass airport!
Bourbon, lemon juice, maraschino liqueur and pineapple juice it is!!!
