1But how do u bring 1 here........u are allowed to take just 4 factors.........and u can't alternate any 3 with the factor "1"
1:D
nice joke.
I thought that you had understood what u were doing in your post #2
1But Philips , p x q x r x s is given....u can't put 1 here ...it won't match with r.h.s ...........try to do it boss
1I think the answer is 256.
210 = 2 x 3 x 5 x 7
Now when p =2 , q=3, r=5, s=7
so p can have vals. 2,3,5,7 and so can each of q, r and s
So no. of solutions is 44 = 256
1yes aveek..philip put the right argument in "you all are ignoring the case when p q r s can be 1"
thnx guys..:):)
1here there is no constraint for any expression.........all expressions can be assigned any values, right eurie ?
1no the answer is 256.
you all are ignoring the case when p q r s can be 1
1the asnwer as given by brilliant is 256...but i feel strongly its wrong
see the way u r telling it is like p=q=r=s can be a solution!!
1but when p has the value 2...q cannot have it....so suppose u put pqrs as 4 hairs...n den u will have MR.2 3 5 7 to sit on them!!which can be done in 4! ways???
