Step 1: Understanding currency deposit ratio.
The currency deposit ratio is a financial term that refers to the ratio of currency (CU) held by the public to the deposits (DD) in banks. It is used to assess the liquidity in the economy. A high ratio indicates that the public prefers holding cash over making deposits in the bank.
Step 2: Analyzing the options.
(A) CU/DD: Correct. The currency deposit ratio is calculated by dividing the currency (CU) by the deposits (DD).
(B) DD/CU: This is incorrect as it represents the inverse of the currency deposit ratio.
(C) DD × CU: This is incorrect, as the currency deposit ratio is a simple division, not multiplication.
(D) None of these: This is incorrect because the correct answer is (A).
Step 3: Conclusion.
The currency deposit ratio is calculated as CU/DD. Therefore, the correct answer is (A) CU/DD.
