What was the puzzle?
We need to go backward to get the answer.
3. At third sister's home he had 2000 + 5000 = 7000. So before visit he had 7000 / 2 = 3500.
2. At second sister's home he had 3500 + 2000 = 5500. This 5500 were doubled from his existing 2750 by her second sister.
1. At first sister's home he had 2750 + 2000 = 4750. His first sister had added 4750 / 2 = 2375 to his wallet in which there were Rs. 2375 already.
So Mayank took Rs. 2375 with him in his wallet while he left home.
However, Mayank must had idea of that his sisters added money to his wallet without his attention.
A donkey travels the exact same distance daily. Strangely 2 of his legs
travels 40 kilometers and the remaining two travels 41 kilometers.
Obviously 2 donkey legs cannot be a 1km ahead of the other 2.
The donkey is perfectly normal. So how come this be true ?

What was looking abnormal?
The donkey is moving on a circular path. Hence, his 2 legs on right (or left depending on moving clockwise or anticlockwise) moves along a circle having lesser radius than circle on which left legs are moving. The difference in circumferences of circles accounts the difference in distance traveled.
This is my favorite puzzle which I had read in a newspaper. It really makes you to think more & more logically to get the answer. I had posted it back in July but re posting it here.
"The scholarship will be awarded," said the head to three candidates - Chuckles, Wombat & Breeze - "to the winner in this little competition. I am going to chalk a cross, which will be either a green or a red cross. I shall then ask each one who can see a green
cross to hold his hand up; and take his hand down as soon as he can
tell me what his own cross is. He must, of course, be able to explain
how his answer is arrived at. Kindly close your eyes for 10 seconds."
He chalked a green cross on all three foreheads. "Go!"
All three hands shot up in air ; that of Chuckles was almost immediately lowered. "My cross is green , Sir"
How did Chuckle know?
