Olympiad Test: Coding and Decoding - Class 10 MCQ

Taking Z = 2, Y = 3, …… N = 14,
B = 26, A = 27
∴ ZIP = (2 + 19 + 12) × 6 = 33 × 6 = 198
and VIP = (V + I + P) × 6 = (6 + 19 + 12) × 6
= 37 × 6 = 222 
Hence ZAP = (Z + A + P) × 6
= (2 + 27 + 12) × 6
= 41 × 6 = 246

Given 134 → good and tasty
478 → see good pictures
728 → pictures are faint
Hence, 4 → Good and 8 → Pictures.

The logic follows here is:

As the fruits grow on a tree and tree is coded as the sky.
Hence, the correct answer is "Sky".

Furniture is made up of wood and wood is straw (here).

Here DRIVER (6 × 2) = 12
CAR (3 × 2) = 6
ACCIDENT (8 × 2) = 16
∴ PEDESTRIAN = 10 × 2 = 20 

Here

Here
M = 1 3 = 1 + 3 = 4; O = 15 + 1 + 5 = 6; 
B = 2 , I = 9 , L =  12 = 1 + 2 = 3;
T = 20 = 2 + 0 = 2 Y = 25 + 2 + 5 = 7;
X = 2 4  = 2 + 4 = 6; N = 14 = 1 + 4 = 5 
∴ EXAMINATION → 56149512965

Here 2 = 2² + 1 = 5; 4 = 4² + 2 = 18;
6 =  6² + 3 = 39; 8 = 8² + 4 = 68;
10 = 10² + 5 = 105.

We can smell with nose. Here, nose is called tongue
Nose → Tongue.

Here, 

J = 1 = 1 + 0
L = 3  = 1 + 2 
Z = 8  = 2 + 6
T = 2  = 2 + 0

Here, E = 5, I = 9, Y = 25, U = 21 
∴ TRAIN ⟶ 20181914

Here ON = 29 = 15 + 14
and RAT = 39 = 18 + 1 + 20 
∴ COW =  3 + 15 + 23 = 41

AT → 401 ⇒1² + 20² = 1 + 400 = 401
CAT → 410 = 3² + 1² + 20² = 9 + 1 + 400 = 410 
∴ MAT → 13² + 1² + 20² 
= 169 + 1 + 400 = 570 

Here Lion → Deer
Lion is called king of the forest.
