Answer / genius

the ans is 333062500

50 yrs = 50 * 365 = 18250 days

the total earning=1+3+5+7+.......+n
where n=18250

so the sum of arithmetic progression is given by
s= n/2(2a+(n-1)d)
where
s = sum of progression
n = number of terms
a = value of first term
d = difference between 2 terms

so s=(18250/2)(2*1+18249*2)
which gives s=333062500

The correct ans. is 333062500

It's given that we work for 50 years, i.e., 50*365= 18250 days.

if we earn Rs.1 on the first day, Rs.3 on the second day,
Rs.5 on the third day & Rs.7 on the fourth day, means we
square the total no. of days to get the total money we
earned. E.g.

In 1 day, we earn Re.1 (squaring 1)
In 2 days, we earn Rs.3+1 (squaring 2) & so on......
So, squaring 18250 , the ans. is 333062500, i.e., we earn
Rs. 333062500 in 50 years= 18250 days.

My ans. has the shortest explanation & cud be called the
best ans. of all the above.

Answer / vinod gupta

Let n be the no. of days
Then (n*2)-1 gives us the amount that you earn for that many
days.

Since we need to find for 50 years and each year has 365 days
Thus, n = (365*50) = 18250

Therefore on 50 years you get,
(18250*2)-1 = 36500-1 = 36499

This is the amount you earn on 50 years.

But we need to find the total amount that we would earn
after 50 years.

For this we need to add the amount from day 1 till 50 years
i.e; 18250

Thus we have,
1 + 3 + 5 + 7 + 9 + ... + 36499 = 333062500

Thus after 50 years we have Rs.333,062,500

Answer / lava

365*50=18250
sum of n odd no =npwr 2
1+2+3+....upto 18250 terms
so 18250pwr 2=333062500

Answer / ranjith naidu

let us consider first for 10 days = rs.19=x
next for 20 days =rs.39
and so on
it means for every 10 days itis x+20
in next step x will change that is now x=39
and so on
now in 50 years it will be
((50*365*19)/10)+20)=rs.34695
ans:rs 34695
