Answers
Let the amount the man initially had be x
When he reached the first temple, the money doubled. So, the amount now is 2x.
He donates 100. So, balance amount = 2x – 100
This again doubles at 2nd temple. So, he has 2 (2x - 100) => 4x – 200
He gives 100. So, he has 4x – 200 – 100 = 4x – 300
Same process at Temple 3.
It doubles and he has 2(4x - 300) = 8x – 600
He gives 100. So, he has 8x – 700
Again doubling at Temple 4. Thus, he has 2(8x - 700) = 16x – 1400
He gives 100 and has nothing. Thus 16x – 1400 – 100 = 0
=> 16x – 1500 = 0
=> 16x = 1500
Therefore, x = 1500/16 = 93.75
Thus, he started from home with Rs.93.75
