Coding Decoding

From the Venn diagram, we have:
The total number of educated people is represented by the triangle, which consists of:
11 (Educated but not backward)
6 (Educated and backward)
5 (Educated and employed, backward)
3 (Educated and employed, not backward)
To find the total number of educated and employed people, we sum the following:
The people who are both educated and employed:
5 (Educated, backward, and employed)
3 (Educated, not backward, and employed) Therefore, the total number of educated and employed people is: Final Answer: The total number of educated and employed people is (d) 9.

Step 1: Analyze the Code for NATION and EARN
NATION is coded as 467234. Let us map each letter to its corresponding number:
N = 4
A = 6
T = 7
I = 2
O = 3
N = 4
Similarly, EARN is coded as 1654:
E = 1
A = 6
R = 5
N = 4
Step 2: Apply the Same Coding Pattern to ATTENTION
Now we apply the same pattern for the word ATTENTION:
A = 6
T = 7
T = 7
E = 1
N = 4
T = 7
I = 2
O = 3
N = 4
Therefore, ATTENTION is coded as 677147234. Final Answer: The correct code for ATTENTION is (D) 677147234.
