Equating the amount at the end of 3 year,
12820 = x ( (1.1)^2+2*(1.1) +3) =6.41 x. Hence x =2000.
@MI8888 Hence hi to hai bhai.. due 3 years hence ka matlab hi wohi hai.. ki 3 saal baad.. mujhe tum 12820 dena... bas !

That's okay but why are we taking CI here ? Why not SI

Arre installments ki value hi differ kar rahi h..SI kasie hoga

I have an explanation if the answer is 2000.
SI le k koi option nai match kar raha..'none of these' bhi nahi hai..isliye CI le lo!

CI mei bhi same instalment se sakte hai..:S

Sorry, par yeh logical nahi:|
2000 and 1800 nai ho sakta..
coz if 1st instalment 1800, second has to 3600 and third has to be 5400..less than principal
1st yr-2000 second yr-4000 3rd yr 6000.total 12000.less than principal
FINAL SOLUTION (JANHIT ME JAARI)
Total Amount to be given after three years = 12820 Rs
Here, the question says starting first year -> THIS WAS MY ORIGINAL DOUBT, but it seems logo ne kuch aur hi kar diya ..
Case 1: Starting 1st year means I start paying now
x*(1.1)^3 + (2x)*(1.1)^2 + (3x)*(1.1) = 12820
-> x*[7.051] = 12820 => x = 1818.2 Rs.. = 1800 approx...
Case 2: Starting 1st year means I start paying after one year
x*(1.1)^2 + (2x)*(1.1) + (3x) = 12820
-> x*[6.41] = 12820 => x = 2000 Rs
Original source had : starting after 1st year
I am sorry that itna confusion create hogaya yahan :splat:

I give it to you, on the point that it is not mentioned CI explicitly, a mistake on whoever made that question, it should be. One pointer why I used CI, is that all EMI's are calculated based on CI, rather than SI.
@Ibanez --
The first installment is 1/2 the second installment and the second installment is 2/3 of the third installment. Jab installments hi alag honge toh interest same kahan se aayeaga?? SI nahi ho sakta

Interest same kyu karna hai?
@YouMadFellow said:@saniyamakhijani Interest har saal ka same kyu karna hai ?
Ho hi nahi sakta voh isiliye toh..
SI tab use karoge jab same hi ho... else nahi!
SI tab use karoge jab same hi ho... else nahi!Some amount was lent on 6% per annum simple interest. After one year, Rs.6800 is repaid and the rest of the amount is repaid at 5% per annum. If the second year's interest is 11/20 of the first year's interest, find what amount of money was lent out.
a) 17000
b) 16800
c) 16500
d) 17500
e) None of these

usse kaise farak padna hai instalment pe :S u can do same ques with SI and ans will come 2380. should be valid.
@saniyamakhijani said:Ho hi nahi sakta voh isiliye toh..
I think ho bhi sakta hai.. nahi bhi ho sakta hai.. Mujhe to @aimingCAT12 ka SI reject karne ka logic better laga ! 😐
