Hi Chittaranjan,
Good ones.... going by your answers, I got 3 right....
For the 2nd question, I have a different answer which can also be right....
5+5+5=555.... if you put the stroke on =, it will become 'not equal to'.
The equation will then become 5+5+5 'not equal' to 555
If you treat the above answer as right too, I've scored 100/100!!!
Cheers!
