Correct Answer: 2186102
Solution :
Given:
28373 is coded as 4166146.
Multiply each digit of the 28373 by 2, to get the required code –
2 × 2 = 4; 8 × 2 = 16; 3 × 2 = 6; 7 × 2 = 14; 3 × 2 = 6
So, 28373 is coded as 4166146.
Similarly, follow the same pattern for 19351→
1 × 2 = 2; 9 × 2 = 18; 3 × 2 = 6; 5 × 2 = 10; 1 × 2 = 2
So, 19351 is coded as 2186102. Hence, the second option is correct.
