Tricky question. Please explain
For this I think the answer should be C as
i) 2N is integer is not sufficient as 1/2 is an option
ii)5N is integer is not sufficient as 1/5 is an option

but if we combine both then 2N and 5N can both be an integer when N is an integer as both donot have an LCM other than 1

Hello all, can you please guide how much time shall be given to a quant question ? I take 3 mins average to reach the solution which I believe is more than it should be. Please guide if there are any tips and tricks to reduce this duration. TIA

As you keep practising the right way , the average time per question will decrease. Try to practice mental maths to speed up calculations.

Make sure you properly understand the concept behind the question and what it actually asks

Cyclicity of 4 is 4,6,4,6… that’s why

Cyclicity of 2 3 7 8 is 4, but they got power 2 in the last line.

Q8 (B)... divisibility rule of 4
But are we not dividing the number of hours by 24 and not 4

Hello, I did not understand how 4^2 comes here.
This is a cyclicity concept video I watched.
As per my understanding, these are remainders of powers e.g. 454/4 will leave a remainder of 2 and hence, last digit will be same as 2^2. But with same logic, for 4^222, the last digit should be same a s 4^1. Can you post the original question and its source.

Bro you should take up a course which explains the basics of quant. Otherwise you’ll have a hard time figuring out these things in your own.

I took course at Jamboree. They taught well but wasn’t enough ad it seems cause there are many unexplored questions.

Questions from Jamboree’s book aren’t sufficient to get a very high score.

You need to solve other type of questions as well

Cyclicity is a pretty basic concept really. I’m not sure why jamboree didn’t cover that.

Hi. Yes you should. It seems there are some basic principles such as Pythagorean theorem as I was concept of area and perimeter that are being tested. Other concepts such as area of a circle or area of another figure will sometimes have the formula provided for it. So you don’t need to memorize formulas for geometry but you need to be slightly familiar with day-to-day concepts. It’s nothing special but don’t freak out if you see an area question or similar to the one you linked above
