If R = 18, RUSSIA = 87, then DELHI is equal to

12
45
38
8

The correct answer is (b).

To solve this, we first need to figure out the code that is being used. In this case, each letter is assigned a number based on its position in the alphabet. R is the 18th letter, so it is assigned the number 18. S is the 19th letter, so it is assigned the number 19. U is the 21st letter, so it is assigned the number 21. S is the 19th letter again, so it is assigned the number 19. I is the 9th letter, so it is assigned the number 9. A is the 1st letter, so it is assigned the number 1.

Now that we know the code, we can plug in the letters of “DELHI” to get 45.

Here is a brief explanation of each option:

  • (a) 12: This is the sum of the numbers assigned to the letters D, E, L, and H. However, this is not the correct answer because the code does not assign numbers to letters in alphabetical order.
  • (b) 45: This is the correct answer because it is the sum of the numbers assigned to the letters D, E, L, H, and I.
  • (c) 38: This is the sum of the numbers assigned to the letters D, E, L, and I. However, this is not the correct answer because the code does not assign numbers to letters in alphabetical order.
  • (d) 8: This is the sum of the numbers assigned to the letters D, E, and H. However, this is not the correct answer because the code does not assign numbers to letters in alphabetical order.
