They have just crapped out in the solution.

The right approach is to find the remainder by 20 ( if we find remainder by 10 , we cant be sure of the last digit when we divide by 2 subsequently , as 8 can give last digit of 4 or 9 ) for the product of those 2 nos. and then divide that remainder by 2.

Remainder was 8 , and hence answer is 4.

Can someone post the question that you are referring to?

In one of the Grammar caselets , the first sentence has a fullstop missing and they have passed it off as a correct sentence .

AS mentioned in d solution GCD =2

as product of both no. 's = LCM * GCD of both

so LCM = (3^2003 - 1)*(3^2003+ 1)/2

= (3^4006 - 1)/2

as Last digit of 3^4006 = 3^2

so for last digit of LCM = (3^2 - 1)/2

* cases like last two digits of LCM to be 18 or 38 or 58 or 78 or 98 can be avoided as these yields LCM a odd no. so the answer is 4

Please correct me if i'm wrng...

QA : 99.98 %ileVA : 99.98 %ileOverall : 99.99%ile^^^^ This fetched me an AIR of 2....I guess the results have been uploaded in hurry and so blunders have done in it.OR else Bhaisahab, pakka tukka laga hai. Gambling kari thi maine toh :splat:The 1316 AIMCAT was on the easier side and so highest scores should be in 150s plus I gave it when I was having headache after a full sleepless night. Kuch toh zaroor lotcha hai bhai. PUYs --> Kiska 150s main aaya hai ??In the POLL too, 5 people have scores greater than 120.

bhai paper aasan nai tha... n kuch locha nai.. if u feel ..u wer lucky enugh to get the scores..then u mgt b rgt.. n dun crib abt ur headache n sleepless nights and al..on pg.. woh kisi kai sath bhi ho skta hai..
