The compound can be arranged according to their taste and effectiveness as shown below.
Taste (sweet) Z, U, V, Y, X, WW
Effectiveness (deadly) X, Y, U, W, Z, V
Compound U is sweeter than Y and More deadly and W.
As per question for sweetness,
U is sweeter than V.
1. U > V.
V is sweeter than Y.
2. V > Y.
W is less sweet than X.
3. X > W.
X is less sweet than Y
4. X < Y.
Y is less sweet than U.
5. Y < U.
Z is sweeter than U.
6. Z > U.
From 1 and 2,
7. U > V > Y.
From 6 and 7,
8. Z > U > V > Y.
from 4 and 8,
9. Z > U > V > Y > X
from 3 and 9,
Z > U > V > Y > X > W
Taste (sweet) Z, U, V, Y, X, W == (Z > U > V > Y > X > W)
As per question for deadly,
U is more deadly than Z
1. U > Z.
V is less deadly than Z.
2. V < Z.
W is less deadly than U.
3. W < U.
X is more deadly than Y.
4. X > Y.
Y is more deadly than U.
5. Y > U.
Z is less deadly than W.
6. Z < W.
Now from 1 and 2,
7. U > Z > V
from 7 and 5,
8. Y > U > Z > V
from 4 and 8,
9. X > Y > U > Z > V
from 3, 6 and 9,
X > Y > U > W > Z > V
Effectiveness (deadly) X, Y, U, W, Z, V
It is clear that both Z and U are sweeter and more deadly than V.
As per question for sweetness,
U is sweeter than V.
1. U > V.
V is sweeter than Y.
2. V > Y.
W is less sweet than X.
3. X > W.
X is less sweet than Y
4. X < Y.
Y is less sweet than U.
5. Y < U.
Z is sweeter than U.
6. Z > U.
From 1 and 2,
7. U > V > Y.
From 6 and 7,
8. Z > U > V > Y.
from 4 and 8,
9. Z > U > V > Y > X
from 3 and 9,
Z > U > V > Y > X > W
Taste (sweet) Z, U, V, Y, X, W == (Z > U > V > Y > X > W)
From the above taste (sweet) ranking, we find that Z is the sweetest.
Given, Siya > Priya > Tiya ........(i)
Siya > Riya > Priya ........(ii)
and Riya > Tiya > Diya .........(iii)
On combining Eqs. (i), (ii) and (iii), we get
Siya > Riya > Priya > Tiya > Diya
According to the question,
A + B = C + D; B + D > A + C; A > B
Now, B + D > A + C and A > B
? B + D > A + C > B + C ? B + D > B + C ? D > C
Now, B + D > A + C ? B + D = A + C + K
Also, A + B = C + D ? B - D = C - A
? 2B = 2C + K ? B > C ? A > B > C
D > C
Clearly, each one of A, D and b has more amount than C. Hence, C has the least amount.
According to question,
R is heavier than S but lighter than T.
R > S But T > R
Then T > R > S
P is lighter than S.
S > P
Then
T > R > S, S > P ? T > R > S > P
But information about Q is not given, Hence, either T or Q is the heaviest.
As per question for sweetness,
U is sweeter than V.
1. U > V.
V is sweeter than Y.
2. V > Y.
W is less sweet than X.
3. X > W.
X is less sweet than Y
4. X < Y.
Y is less sweet than U.
5. Y < U.
Z is sweeter than U.
6. Z > U.
From 1 and 2,
7. U > V > Y.
From 6 and 7,
8. Z > U > V > Y.
from 4 and 8,
9. Z > U > V > Y > X
from 3 and 9,
Z > U > V > Y > X > W
Taste (sweet) Z, U, V, Y, X, W == (Z > U > V > Y > X > W)
As per question for deadly,
U is more deadly than Z
1. U > Z.
V is less deadly than Z.
2. V < Z.
W is less deadly than U.
3. W < U.
X is more deadly than Y.
4. X > Y.
Y is more deadly than U.
5. Y > U.
Z is less deadly than W.
6. Z < W.
Now from 1 and 2,
7. U > Z > V
from 7 and 5,
8. Y > U > Z > V
from 4 and 8,
9. X > Y > U > Z > V
from 3, 6 and 9,
X > Y > U > W > Z > V
