- amith total expense is 100*(62+61......+1) and meghana is 100*(1+2+....63).
tola is 100(62+61....+1+1+2+....63) which can also be written as 100(63)+100*2*(62+61....+1)
expense per day is ((100*63)+(200*(62+61+.....1))/63 which gives 6300 result - 12 years agoHelpfull: Yes(11) No(1)

bt both spend 100$ each ...i.e. 200$ total
so 200$*63= 12600
ans is 1. $12600 - 12 years agoHelpfull: Yes(5) No(13)
