@fisherking Nah, I gave MC 1307 or 1308 yesterday.. Kuch khaas nahi gaya. Uske aage ke MCs abhi dene hai. Aaj wo naye waale sectionals mein se ek VALR ka diya, usme bhi random sahi aur galat hue hai. Jo half attempts the wo sahi aur jo soch samajh ke attempt kiye wo galat. 
@YouMadFellow said:I can make oneQuestion : Amount of 2000 is deposited in a bank at an annual rate of interest of 8% p.a. What will be the approximate interest generated after 1.5 years if the interest is compounded every 3 months. ?
hmm....Amount = 2000(1 + 2/100)^6 = 2252.2 (approx.)
@karanthepagal said:@mbajamesbond kaha gayab ho ??
Hi bro, hows prep, not coming online much these days....offline mode mein practice chal raha hai
@YouMadFellow said:How ?What I would do is this:Amount = 2000*(1 + (8/4)(1/100))^6 = 2000*(1 + 2/100)^6Binomial expansion -> Amount = 2000( 1 + 12/100 + 6C2*4/100^2 + 6C3*8/100^3 +..negligible terms)Amount = 2000( 1 + 0.12 + 0.006 + 0.00016)Interest = 2000*(0.12 + 0.006 + 0.00016) = 252.32 ?I don't know whether the answer is correct or not.
'n' aur 'r' dono hi per annum diye hai na..plus according to ur question, n = 1.5yrs.
matlab ki 18 months and it's compounded every 3 months..matlab 6 times in this case. Shouldn't we be modifying the rate and the years with the same factor?
@YouMadFellow said:How can the answer be more than 50% of the principal amount ? 8% is the interest rate. For one year, it will be 160, for one and the half year, it should be close to 160 + 80 = 240.. I am getting 252.32.. Check the post above
Yeah rate of interest is 8 % per ANNUmm, so for for every 3 months it has to be divided by 4 , i get it now. Told you i never tried doing this chapter. :P
@Brooklyn said:power 6 q li hai ??? 1.5 / .3 = 5 yrz naa??
Go, by months => 18 months/ 3 months = 6 !
@rachit_28 said:12/k times a year means...... shouldn't 12/k be equal to 4 ? (as it is given every three months, means 4 times a year), and if that is true k should be 3 but you have taken 4.Please correct me if i am wrong. Thanks
Haan, I made a mistake in writing the formula actually 😃 ..
See, the concept is : how many times in a year do we need to compound.. In this case 3 month period => in a year 4 times.. so the effective interest rate should be 8/4 = 2 %..
@Brooklyn said:power 6 q le rhe ho yar??
basically divide interest by 4 and number of years by 4
(3 months)*6 = 1.5 years

I calculated using (108/100)^ 6 instead of taking the reduced rate. Arey yaar it aint that bad, thoda logic hai isme bhi 😃

Haan to effective 3 months ka interest => 8/4 hua naa = 2 %
Aur number of periods of 3 months = 6 .. Sab kuch ab relative to 3 months kar do

Naye waale main mere saath bhi aisa kuch hua hain.....Aur pehle waale QA sectional main toh timer se mujhe sirf 45 minutes mile poore 30 questions ke liye

1 one :)

Arey I-Bank walon ko to pata hota hai ye sab, but they are ambivalent and amoral 😃

right! oh..rate wale case me confuse ho gayi thi..
