But 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"

But 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

I 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

yes aveek..philip put the right argument in "you all are ignoring the case when p q r s can be 1"

thnx guys..:):)

ans is 44 ..no dbt abt that

1
Philip Calvert ·

no the answer is 256.

you all are ignoring the case when p q r s can be 1

1
RAY ·

the 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!!

1
Bicchuram Aveek ·

wht's the original answer ???

1
RAY ·

but 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???
