i m unable to reply...............toh post krna to dur ki baat hai.........thread nt available ke link pr click krne pr bhi reply post nhi hua..............

to all
i will suggest you to bring question on HCF and LCM tmrw..

i wont bring more than 5 question.. rest you guys have to bring..it takes my too much time to do all this thing and all the questions are already done by me..

so if you guys will share also than i will be interested or else.. i will stop ..

4 aayega.
cyclicity use karni hai

first wala half hai and 2nd wala 1 and half hai

@coolparul007

ohh u are thinking it multiply no re im writing it as there se no way to write mixed fraction
1(1/2) = 3/2

Unit digits of 7 and 3 both gets repeat after squaring 4 times

3,9,7,1 - For squares of 3
7,9,3,1- for squares of 7

7^95 = {(7^4)^23} * 7^3 =1* 7^3 = 343 (we are taking digits up to 3 places in this case because in question we have to find difference between two ...if product has to find, we would have taken only 3(unit digit) from 343)

Same with 3^58= {(3^4)^14} *3^2 = 1 * 9= 9

7^95 - 3^58 = 343-9= 4 at last digit.

Q5
what no. should be added to 231228 to make it exactly divisible by 33.
need shortest way to calculate this.
so please give reasons in supprt of ur answers.
if this no. is exactly divisible by 33 than this no. has to be divisible by 11 and 3 both 231228 is divisible by 3 but it gives reminder 8 when diveded by 11 so if we add 3 than it also divisible by 11

this qustion done by cyclicity method cyclicity of 7 and 3 is 4 than ans is 4

hii everyone...can i join u guys??? took some time to put myself togather after d SSC mains....will keep trying and not loose hope...:)

sry my mistake..........pr paper mein bhi aise hi options aayenge to kaise pta karange ki mixed term hai ya multiply kra hai.......

paper main subset aur superset types aata hai toh distinguish kar sakte hai and they use * or X for product
