HELLO SIR,

GIVE ME GUIDENCE FOR DISCRIPTIVE TEST OF NICL AO EXAM

at what rate percent compound interest does a sum of money becomes ninefold in 2years

its 200%.

1000 after 1 year becomes 3000 which again after 1 year becomes 9000 in CI

in 1 year it becomes 2000 only so the answer is 300%

Hope u know the formula for CI

Sum of money at CI=P*{(1+R\100)^n}

Assuming the sum of money in starting to be Rs.X at R rate of interest, equation becomes

9X=X*{(1+R\100)^2}

or 9=(1+R\100)^2

or 3=1+R\100

or 2=R\100

or R=200% p.a.

Cheers.

What a comprehensive coverage! thanks for this great work

please provide sebi officer grade A exam previous question paper.

thankx sir

nice

Dear Mrunal your process of solving time and work problem was really helpful.Can u plz give the solution of this problem in STD process.A, B and C can do a piece of work in 20, 30 and 60 days respectively. In how many days can A do the work if he is assisted by B and C on every third day?

Do u mind if I solve this prblm in place of Mrunal? Here’s the solution

We find out the work done in set of three days since A is assisted by B and C on every third day.

A completed work in 20 days, thus his contribution per day will be 1\20 in one day.

Since in these three days A works for all three days, his contribution will be 3*1\20=3\20 of the work

Also since B and C work on only third day, their contribution similarly will be 1\30 and 1\60 of the work.

Hence adding the work done in three days=3\20+1\30+1\60=1\5=0.2 of the work.

Thus this is the portion of work completed in a set of 3 days. Hence to complete the work, 5 such sets will be required (1.2)

hence total number of days will be 5*3=15 days.

Cheers.

your service is very useful for those who r in remote areas where coaching is not available thanks a lot

Mrunal Sir i am preparing for ibps po.Can you plz provide the trick to solve qsns like:-

Q1) 6894.986+5025.005+600.020= ? and

Q2) 40.005% of 439.998+ ?% of 655.011=228.5

in a quick way.

Sir, thanks for providing with these superb material. sir, what i’ve wanted to say, is if you can provide some RCs on Paper 2 of prelims for the practice. or you can suggest some sites where one can find free RCs for prparation. I’ve given 2 attempts but both time i couldn’t clear the Prelims. as much i’ve analysed, i’m lagging in Paper 2. Sir, kindly please do provide something on this.

sir,firstly i want to say thank you,,,because you maintained a nice site and it it fully updated,i am saying fully because u seem to do a lot of work on it.i had given the recent exam of ibps rrb but i was confused to whether i have to attempt english or hindi or both,and i asked invigilator but he doesn’t gives the satisfactry answer but till then i have attempted 182 questions out of 240.i don’t think that i will select but due to lack of information i faced a huge problem,so i want to thanks again to you to maintain this site and providing information about all the topic,,,keep it sir,,,your work is best as i seemed,,its time 2:00 am and till now i am writing because or your good site,,appreciated work…keep it up…

mrunal sir i need a solution of how to find values from these kind of questions quickly..

x+1/x=3 then x^3+1/x^3=?

similarly

x+1/x is not equal to 0 then (x+1/x)^4=?

plz give me a solution sir..

Pls read the formula for (a+b)^3 = a^3 + b^3 + 3ab(a+b)

Appying it here,

(x + 1\x)^3=3^3

x^3 + 1\x^3 + 3*x*1\x(x + 1\x)=27

x^3 + 1\x^3 +3(x + 1\x)=27

x^3 + 1\x^3 +3*3=27

x^3 + 1\x^3=27-9

x^3 + 1\x^3=18

The problem is not clear, needs correction

Cheers

sir,

plz. give me data entry operator Quantitative Aptitude all formulas……..

When X is subtracted from the numbers 9,15,27,the remainders are in continued proportion. what is the value of X?

Considering u know what is Continued proportion

Decrease 3 from all the numbers. The remainders will be 6, 12 and 24 which are in continued proportion as 6:12:24 where the ration of 6:12 and 12:24 is same.

Cheers
