bhai yahan total volume increase hoti zaa rhi hai......so can we apply this formula or series bana ke karna padega
yaar vo ratio wala mera bahut calci aa raha h

short method
@mickym said:
bhai use division method
bhai it is common meyhod any other method

pranaam bnadhu log....mann nahi lag rha tha isliye aa gaya

ye sign kya represent kar rha hai
@micky0007 if number is not big..den factorise both of them and HCF can be found easily...

if numbers are big and complex and usk factors nhi mil rahe hai,dn use d good old division method which we used in school

Bhai this is the shortest.......works very well when u r unable to find factors easily

Baki methods i don't knw yaar

HCF the only possible simple way and also quick is
by writing its prime factors
and taking all the powers which are common in all

Bhai i did this........but thoda tym laga

30*((1- (10/30))*(1-(10/40))*(1-(10/50)).......(1-(10/100))

Bhai formula nhn chalega yahan logic chalega

ye dekho
30*((1- (10/30))*(1-(10/40))*(1-(10/50)).......(1-(10/100))
@mickym said: Brass is an alloy of Cu and Zn. Bronze is of Cu(80%), Zn(4%), Sn(16%). A fussed mass of both has Cu(74%), Zn(16%), Sn(10%). What is the composition of Cu and Zn in Brass ?
58.4 gm-cu
21.6gm-zn

yeh answer sahi h kya?because kuch caluclation mistake lag rhi h :(
