breaking the above question
first multiplication part..

why*t=oonp
why*u=oypy
why*n=ouha
now since we are getting 'o' in the above three multiplication on the xtreme left side it must be one only..
so taking 'o'=1
we get..
why why why
* t * u * n
---- ---- ----
11np 1ypy 1uha

(1) (2) (3)
now carefully xamining the above multiplications..in (2)multiplication when y is multipliedby u it is giving y only...dat means y can be 0 or u must be 6, but in the (1),(3) part when y is multiplied by t and n resp it doesnt gives y so dat means y could not be zero hence u must be 6 because as we know..
6*2=12..at once place 2.. i.e the same nos by which 6 is multiplied..
also 6*4=24..once place 4..
6*6=36...once place 6..
so 6*y=y...once place y...
hence u =6 and y must be some even nos...bcz the above logic of 6 is only applicable for even nos multiplied by u 6 and not for odd nos multiplied by 6..
now again placing value of u in part (1),(2),(3)..
now moving to addition part..dat is...
oonp p=p
+ oypy placing o=1 n+y=o
+ouha u=6 and splitiing addition 1+p+a=p
-------- 1+y+h=e
onepop 1+6=7 which is n ,so n is 7
-------- 1=1
17ep1p

now again by putting values of o,u and n in 1,2,3 multiplication part and by using addition equations side by side we will get the answer as
o=1 ,u=6 ,n=7,y=4,a=8,p=0,h=3,w=2,t=5,e=9
the above answers ,we will get dese solutions in the same order as written above...kk
i thnk dis is enough for xplanation part..by hit and trial...only we can easily get the desired result...hope it is helfull...

in a strange twist of hearts ,p politicians of a country agreed to an average donation od rs.D each.Q of these poloticians ,who had pledged an averageof rs.A never donated the pledged mooney .which of the following expressions represents the percent of the pledged money thas ws actually donated
a)100(QA/PD)
b)100(PD/QA)
c)100-100(QA/PD)
d)100PD-100(QA/PD)
c)100-100(QA/PD)

pledged money = p*D
Actually donated money = pD-QA

percent of the pledged money thas ws actually donated = 100*(pD-QA)/pD = 100-100(QA/PD)

c) 100- 100(qa/pd) actually pledged amount is p*d=pd but q people didnt donated
q*a=qa.so pledged amount is pd but qa of pd was not donated...so actually donated amount is pd-qa.so % of actually pledged amount is ((pd-qa)/pd) *100
