- plz explain d solution. 19 Jul '13.

u can do by options . but let us see the long way. let CP be x. So SP is 1.1x. New CP = 0.96x and new SP is 1.1x+6. Now (1.1x+6)/(0.96x) - 1 = 18.75%=0.1875=> (1.1x+6)/0.96x = 1.1875=> 1.1x+6 = 1.14x=> x= 150

I just consider the case of - 13/5+10/3=89/15=>remainder - 14..

and now 13 mod 5=3 and 10 mod 3=1 so 3/5+1/3=14/15 again 14 remainder..so

(173*261) mod 13= 4 and (248*249*250) mod 15=0..

4/13=4..4 should be ans..calculation mistake in previous 1.

OA kya hai?@felis.catus

and now 13 mod 5=3 and 10 mod 3=1 so 3/5+1/3=14/15 again 14 remainder..so

P&L; is one of those topics where you can always save a lot of time (to be used in other questions)....

it's perhaps one of the easiest of the topics to cover..... I'm a 100 percentiler in quant and have made a few videos.... you can use them..... don't use them for any commercial purposes (it's a request) and of course you can pass on the word if you like....

Since I'm in middle of my preparations for civils, I haven't made videos on all the topics, yet there are enough to get the basics right.....

I'm posting the one on P&L; - (excuse me for my handwriting

Profit and loss is the branch of basic mathematics which deals with the study of profit and loss made in a business transaction.Profit and loss is mainly used in finance and business transactions.Some important profit and loss formulas are :Notations used in profit and loss:S.P. Selling priceC.P. Cost priceM.P. Marked PriceProfit and Loss Formulas:1. Profit or Gain = S.P. C.P. [ profit is made only when S.P. is greater then C.P.]2. Loss = C.P S.P. [ Loss id made only when C.P. is greater than S.P.]3. Profit % = (Actual Profit C.P. ) 100%4. Loss % = (Actual loss C.P. ) 100%5. C.P. = (S.P. 100 ) (100 + profit%) [If profit is made]6. C.P. = (S.P. 100 ) (100 profit%) [If loss is made]7. S.P. = (100 + profit%) C.P 100 [If profit is made]8. S.P. = (100 loss%) C.P 100 [If loss is made]9. Actual Discount = M.P. S.P.10. Discount% = (Actual Discount M.P.) 100%11. S.P. = M.P. Actual Discount12. S.P. = M.P. Discount% of M.P.13. S.P. = (100 Discount%) of M.P.

Are there any shortcut methods to solve questions like If the principal is 22000, the rate of compounded interest is 12%. what would be the amount after 4 years if the interest is calculated quaterly???

(i do it by long method bt it takes a lot of tm)

Ummmm not exactly shortcut but vedic maths can be of great use here.... as in the concepts related to squares..... you can easily ace them...... and wrt SI/CI, there are some really tough questions that have been asked in CAT.... will try writing about it sometime soon... and about Vedic maths you can watch this video (if you haven't learnt the concepts earlier).....

All the best :)
