Brother, since we are not given any information about "n"(even or odd), we can only take a-b to be a 'certain' factor of given expression, so answer according to me would be 101-1=100
The book is our beloved M.Tyra

Pavi, please post the right answer of this question.

@anticipator.lad
I got it through binomial expansion.

You are correct, 'largest' divisor would be 10000 only.

Though through the concept explained in M.Tyra 100 would certainly be a divisor as implied form the ans i.e, 10000.

10,000 is the rite ans...
(101^1 - 1) to (101^9 - 1) will be divisible by 100
(101^10 - 1) to (101^99 - 1) will be divisible by 1000,
therefore (101^100 - 1) will be divisible by 10,000.

buddy there is a direct formulae for these kind of question

{1+(4a+1)^1/2}/2

here a=6 put that you will get the answer

A took 2 loans altogether of 1200 from B and C. B claimed 14% simple interest and c claimed 15% per annum. total interest paid by A in one yr was 172. then A borrowed.....

a) 800 from c
b)625 from c
c) 800 from b
d) 400 from b

d)3012
3011* (3011+1)
= (3011*3011) + 3011
= 3011^2 + 3011

so 3011 is the least required number we are looking for.

a) 800 from c
b)625 from c
c) 800 from b
d) 400 from b
Let A took loan 'x' from B and (1200-x) from C.

Total Interest paid by A to B + Total Interest Paid by A to C = Rs.172

=>{ (x * 14 * 1 ) / 100} + [{1200- x} * 15 * 1 } / 100] = 172

solve for x; we get x= 800; i/e/ 800 loan from B and 400 from C
