IMO the question is incorrect

in option A it should be D(1) = 11000

the Ans is D


Even if its not D(1)
the ans will still be D

could u please solve this ??

Hi Vishu,
This is a data sufficiency question category,so solving would waste the time

Consider statemnt 1

D(t) = 11,000 ie D(1) = 11,000(as per the data given in the question)

so here t =1 and D(1)=11000 applying the values in the given formula

D(t) = 10,000
{1+(r/100)}t

we will get the value of r,once we find r we can always get the amount after 3 years by reapplying all teh value sback in the formula

so A is sufficient


Consider choice B

(2) r =10

here in also you can directly find the amount value after 3 years

cincre r = 10 ,n=3 so you will get D(3) value

Hence B is also sufficient

Hence the final answer would be D,since each of them is individually sufficient

Thanks

Vishu..FYI, you may post the DS problems in the DS section.
