Happy new year. Recheck your solution. I m 100% sure about this solution.

Taking the summation backward from the 9th temple.

Before ascending the 9th temple, he had
100(back to the top) + 100(since he dropped half of the money)+ 100 (before ascending)= 300coins

In the same manner,
Before ascending the 8th temple, he had
2(300+100)+100= 900coins

Before ascending the 7th temple, he had
2(900+100)+100= 2100coins

Before ascending the 6th temple, he had
2(2100+100)+100=4500coins

Before ascending the 5th temple, he had
2(4500+100)+100 = 9300coins

Before ascending the 4th temple, he had
2(9300+100)+100= 18900coins

Before ascending the 3rd temple, he had
2(18900+100)+100 =38100coins

Before ascending the 2nd temple, he had
2(38100+100)+100= 76500coins

Finally before ascending the first temple/embarking on the journey, he had
2(76500+100)+100= 153300 coins

Starting from the ninth temple to the first to make the calculation easier:

Total Amount had = Amount spent + Amount leftover

Let (Y) be the Total amount he had

For the ninth temple:
Amount spent = 100 + (Y-100)/2 + 100
Since he gives 100 coins climbing up, Half of what is left(after deducting 100) to the priest and 100 climbing down.

Amount left over = 0

Using the formula above :
Total Amount had = Amount Spent + Amount leftover
Note: Y = Total Amount had
Therefore Y = (100 + (y-100)/2 + 100) + 0
Y = (200 +(y-100)/2)
Cross multiply or multiply each value by 2
2y = 400 + y - 100
2y = 300 + y
Take like terms
2y - y = 300
Y = 300
Therefore total amount had at ninth temple is 300

For eight temple.
Also apply the formula :
Y = (100 + (y-100)/2 + 100) + 300
Y = 200 + (y-100)/2 +300
Cross multiply or multiply each value by 2
2y = 400 + (y-100) + 600
2y = 1000 + Y - 100
Collect like terms
2y - Y = 900
Y = 900
Therefore 900 at eight temple

For seventh temple :
Y = (100 + (y-100)/2 + 100) + 900
Y = 200 + (y-100)/2 + 900
Cross multiply
2y = 400 + y - 100 + 1800
Collect like terms
2y - y = 1800 + 400 - 100
Y = 2100
Therefore 2100 at seventh temple.

For sixth temple :
Y = (100 + (y-100)/2 +100) + 2100
Y = 200 + (y-100)/2 + 2100
Cross multiply
2y = 400 + y - 100 + 4200
Collect like terms
2y - y = 400 - 100 - 4200
Y = 4500
Therefore 4500 at sixth temple.

For fifth temple :
Y = (100 + (y - 100)/2 + 100) +4500
Y = 200 + (y-100)/2 + 4500
Cross multiply
2y = 400 + y - 100 + 9000
Collect like terms
2y - y = 400 - 100 + 9000
Y = 8700
Therefore 8700 at fifth temple.

For fourth temple :
Y = (100 + (y-100)/2 + 100) + 8700
Y = 200 + (y-100)/2 +8700
Cross multiply
2y = 400 + y - 100 + 17400
Collect like terms
2y - y = 400 - 100 + 17400
Y = 17700
Therefore 17700 at fourth temple.

For third temple :
Y = 200 + (y-100)/2 + 17700
Cross multiply
2y = 400 + y - 100 + 35400
Collect like terms
2y - y = 400 - 100 + 35400
Y = 35700
Therefore 35700 at third temple.

For second temple :
Y = 200 + (y-100)/2 + 35700
Cross multiply
2y = 400 + y-100 + 71400
Collect like terms
2y - y = 400 - 100 + 71400
Y = 71700
Therefore 71700 at second temple.

For the first temple :
Y = 200 + (y-100)/2 + 71700
Cross multiply
2y = 400 + y - 100 + 143400
Collect like terms
2y - y = 400 - 100 + 143400
Y = 143,700

Summary :
Ninth temple = 300
Eight temple = 900
Seventh temple = 2100
Sixth temple = 4500
Fifth temple = 8700
Fourth temple = 17700
Third temple = 35700
Second temple = 71700
First temple = 143700

I hope am correct

You missed it from the the fifth temple

Collecting like terms should give you
2y-y= 400-100+9000
y=300+9000= 9300

146900
Explanation:
Whenever you face such type of questions, it is
wise to begin from the last thing. Here in this
question the last thing will be the 9th temple.
He climbed down 100 steps and thus you
know, he had Rs. 100 before beginning
climbing down. Thus, he must have offered Rs.
100 to the god in that temple too (he offered
half of the total amount). Also, he must have
dropped Rs. 100 while climbing the steps of the
ninth temple. This means that he had Rs. 300
before he begand climbing the steps of the
ninth temple.

Now, we will calculate in the similar manner
for each of the temples backwards.
Before the devotee climbed the eight temple:
(300+100)*2 + 100 = 900
Before the devotee climbed the seventh temple:
(900+100)*2 + 100 = 2100
Before the devotee climbed the Sixth temple:
(2100+100)*2 + 100 = 4500
Before the devotee climbed the fifth temple:
(4500+100)*2 + 100 = 9300
Before the devotee climbed the fourth temple:
(9300+100)*2 + 100 = 18900
Before the devotee climbed the third temple:
(18900+100)*2 + 100 = 38100
Before the devotee climbed the second temple:
(38100+100)*2 + 100 = 76500
Before the devotee climbed the first temple:
(76500+100)*2 + 100 = 153300

Therefore, the devotee had Rs. 153300 with
him initially.

Annnikky there's a small mistake here.
(2100+100)*2 +100
(2200)*2 +100
4400 + 100
= 4500. Not 4300

BTW how did you guys generate this method: (300+100)*2 + 100 = 900
Please explain, thanks.
