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

Answer / abhishek gupta
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 / siddheshwar mali
he 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

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

Eleven boys and girls wait to take their seats in the same row in a movie theater. There are exactly 11 seats in the row. They decided that after the first person sits down, the next person has to sit next to the first. The third sits next to one of the first two and so on until all eleven are seated. In other words, no person can take a seat that separates him/her from at least one other person. How many different ways can this be accomplished? Note that the first person can choose any of the 11 seats.

The son of a rich bullion merchant left home on the death of his father. All he had with him was a gold chain that consisted of 138 links. He rented a place in the city center with a shop at the lower level and an apartment at the upper level. He was required to pay every week one link of the gold chain as rent for the place.
