Answer is 333 ]]>

a) 17

b) 31

c) 106

d) 247

e) 353 ]]>

If 3^m + 3^n + 3^p = 3^q, then

m = n = p is the only possibility

3^(2x)+3^(3y)+(3^5z)=3^7z

2x=3y=5z

3^(2x+1)=3^7z

so 2x=7z-1

2x=3y=5z=7z-1=k

so x=k/2 , y=k/3 , z=k/5 , z=(k+1)/7

k=90

so x+y+z+w=106 ]]>

a) 44

b) 43

c) 23

d) 22

e) 5 ]]>

for a number consisting of 4s to be divisible by 9

the 444.... has to have 9 4s

so 444444444 / 18 = 24691358= 8 digits ]]>

a) 30

b) 40

c) 50

d) None of the above ]]>

f(k) = 2k if k is odd

= k/2 if k is even.

if f(f(f(k))) = 22 then find the sum of all possible values of k. ]]>

f((f(k))=11 or 44 (( 11 odd so we will get 22 or 44 even so we will get 44/2=22

case= f(f(k)=11

then f(k)=22 (K if even then k/2 ,)

when f(k)=22

then k=44 or 11

When f(f(k)=44

then f(k)=88 or 22

when f(k)=22 then k=44 or 11

f(k)=88 then k=44 or 176

so k=11,44,176

so sum 11+44+176=231 ]]>
