# Solutions with Explanations for Coding-Decoding Problems

Friends, here are the solutions for our Coding-Decoding Practice Problems. Please check the problems from here and try to solve on your own before checking these solutions.

### Set 1 Solutions

1.  (3)
All the letters in the words are arranged in alphabetically increasing order.

2. (1)
GUST = @7\$2 ------------------------ (i)
SNIP = 957#  ------------------------ (ii)
GAPE = {\$35 ------------------------ (iii)
From (i) and (ii), S = 7 ------------------------(iv)
From (i) and (iii), G = S  ------------------------(v)
From (ii) and (iii), P = 5  ------------------------(vi)

From (ii) and (iv),
SNI = 97#  ------------------------(vii)
Now, combine (v) and  (vii).

3.(3)

4. (3)
The colour of clear sky is blue.
But here blue is called yellow.

### Set 2 Solutions

Directions (1-4) :
ze lo ka gi = must save money (i)
fe ka so ni = he made good money (ii)
ni lo da so = he must be good (iii)
we so ze da = be good save grace (iv)
from (i) and (iii), lo = must (v)
from (i) and (iv), ze = save (vi)
from (ii), (iii) and (iv), so = good (vii)
from (i) and (ii), ka = money (viii)
from (i), (v), (vi) and (viii), gi = some (ix)
from (ii), (iii) and (vii) ni = he (x)
from (ii), (vii), (viii) and (ix), fe = made (xi)
from (iii), (v), (vii) and (x),
da = be (xii)
from (iv), (vi), (vii) and (xii), we = grace (xiii)

### Set 3 Solutions

1. (3)
 P K D E J H I 7 1 2 6 5 3 9

Since E is neither at the beginning nor at the end it is coded as '6' and I is at the end, so by 9.

2. (1)
 A F D Q E N I 9 7 2 8 6 4 9

3.(4)
 O P T I O N A L 9 7 1 6 6 4 6 3

4. (5)
 E G T A R L O E \$ 5 1 6 5 3 8 \$

5.(3)
 E N I A N G E \$ 4 6 6 4 5 \$

### Set 4 Solutions

Directions (1-4)

 Group Elements # 1 A, B, C, D #2 E, F, G, H #3 I, J, K, L, M, N #4 O, P, Q, R, S, T #5 U, V, W, X, Y, Z

 Group Value Assigned  to each letter of the group # 1 10 #2 20 #3 30 #4 40 #5 50

1. (2)
 Element Group Value B #1 10 E #2 20 * 2 G #2 20 * 2
Thus, the value of the word "BEG" = 10 + 40 + 40 = 90

2. (3)
 Element Group Value Q #4 40 U #5 50 * 2 E #2 20 * 2 U #5 50 * 2 E #2 20 * 2
Thus, the value of the word "QUEUE" = 40 +100 + 40 + 100 + 40 = 320

3. (1)
 Element Group Value S #4 40 P #4 40 O #4 40 T #4 40 S \$4 40

Thus, the value of the word "SPOTS" = 40 * 5 = 200

4. (5)
 Element Group Value H #2 20 I #3 30 * 2 G #2 20 H #2 20

Thus, the value of the word "HIGH" = 20 + 60 + 20 + 20 = 120

5. (5)
 Element Group Value S #4 40 H #2 20 * 2 O #4 40 T #4 40

Thus, the value of the word "SHOT" = 40 + 40 + 40 + 40 = 160

1. hi mam..you want to apply a diference between "%"and "/" symbols ...because these symbols are changing the answer..in 5 th question there %=(1/100) then answer is coming 5/8..change apply

2. 8 th question is wrong

3. thanks
