Answer / sumit kumar
10+20+40+80+160....
10(1+2+4+8+16..............)
this is a gp
first term=a
ratio=2
t21=1*2^20
given*******
1/32 of x=2^20
x=2^25
therefore in gp
Tn=ar^n-1
n-1=25
n=26
=26

Answer / sushma baradwaj
1 of the 32 parts is filled in 21 hrs...
as the level gets double per every hour..
1....1*2..2*2(4)...4*2(16)..16*2(32)
so it will take 5 more hours to fill d tank completly
hence 21+5 = 26

Answer / saurabh singh
Solution: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8)th part in 23 hours,(x/4)th part is filled in
24 hours,
(x/2)th part is filled in 25 hours, (x)th part is filled in
26 hours
So answer is 26 hours.

Answer / sherley
Given that B fills up at the rate 10, 20, 40 etc...
This is a geometric progression where a = 10 r = 2
so after 21 hrs liters in B = a*r21 = 10 * 221
This is equal to 1/32 volume of B
SO TOTAL VOLUME OF B = 32 * 10 * 221 which is =10 * 226
So hrs required to fill up B is 26

Answer / siddarth
The given fraction part is 1/32 or (1/2^5)
as given series is 10(1,2,4,8,16...)or 10(2^0,2^1,2^2,2^3,2^4,2^5..) in the series we got 2^5 as after 5 hours.
so after 21 hours from 5 hours i.e 21+5=26 (ans=26)
