@lalit6600 great to see U people sweating so hard for preparation

A humble suggestion saw Ur questions very nice but on the lines of CGL we had cutoff of 82 in CGL but it would be atleast 110 in FCI & 115-120 in CHSL so again try to do easy questions in less time

ATB

@lalit6600 bhai dekho meri baat ka bura mat manana maine last year FCI clear kiya tha till DEST so I know level of paper U guys are preparing way higher its a good practise but may result in quality than quantity which happens vice versa in these two papers FCI & CHSL yaar easier q kam samay me karo

as for practise paper I will look on net & would upload when I find anything

@sampras Thanks for the reply ,but ye to preference pe depend karega na, and there is no option to select Delhi as first pref......
Bhai Delhi is coming in North Zone refer page 12/36 of the notification...
http://ssc.nic.in/notice/examnotice/FCI%20Notice%20final2.pdf ..... so if one opts for North Zone there is chances of getting Delhi Zone if coming under merit...and even if not getting Delhi can be any where in North Zone ,... and within Zone transfers can be easily got done...that's not a big issue...

Find out LCM of 4^5,4^-18,4^12,4^7 .


1. 4^-81
2. 4^5
3. 4^7
4. 4^12
517
the HCF and LCM of two numbers are 21 and 4641 respectively . If one of the numbers lies between 200 and 300 , the two numbers are -
a. 273,357
b. 210,340
c. 215,314
d. 210,252

always product of two nos is product of lcm and hcf
so just check no which have last digit of their product 1 as hcf and lcm will have their product last digit 1
only a satisfies the condition

Formula:- HCF*LCM = Product of two numbers
21 * 4641 = Last digit will give 1
in options
Product of which option is giving last digit as 1 is A only.
So ye A aa gaya aapka answer.
great short cut ,,, no need to do all calculations .. thanks bro

Bhai... LCM is the multiple of highest power or if the base are same and powers are only changing then also, Base will be the same and power will be the highest one.

In this scenario, the highest power is 4^12... isliye ye answer hai....


Example: LCM of 2,4 and 8 is 8

i.e. 2^1 , 2^2 and 2^3 is 2^3
