Since, he must have offered 100 coins while climbing down stairs, it means that he must have offered Rs. 100 to god on the ninth temple and offered Rs. 100 while climbing up steps. Thus it is clear that he had Rs. 300 in his pocket before climbing the steps of the 9th temple.<br /><br />Similarly, we will calculate for all the temples backwards.<br />Before eight temple: (300+100)*2 + 100 = 900<br />Before seventh temple: (900+100)*2 + 100 = 2100<br />Before Sixth temple: (2100+100)*2 + 100 = 4300<br />Before fifth temple: (4300+100)*2 + 100 = 8900<br />Before fourth temple: (8900+100)*2 + 100 = 18100<br />Before third temple: (18100+100)*2 + 100 = 36,500<br />Before second temple: (36500+100)*2 + 100 = 73300<br />Before first temple: (73300+100)*2 + 100 = 146900<br /><br />Therefore he had Rs. 146900 initially.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-1672133381132607462014-05-21T14:40:13.628+05:302014-05-21T14:40:13.628+05:30i lakh what you did there anonymous ;)i lakh what you did there anonymous ;)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-69955019542332234842014-05-21T12:38:09.062+05:302014-05-21T12:38:09.062+05:301,27,700/-1,27,700/-Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-1825389745761460772014-05-21T01:08:01.181+05:302014-05-21T01:08:01.181+05:30127700 ... presumably sacrifice to god takes place...127700 ... presumably sacrifice to god takes place at top of stairsAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-40324746117485818812014-05-21T00:52:19.731+05:302014-05-21T00:52:19.731+05:30He originally had 51100 coins.He originally had 51100 coins.Anonymousnoreply@blogger.com
