Suppose an initial cash deposit of INR 100 crores has been made in a commercial bank where a total credit of INR 500 crores has been created in the economy. The required reserve ratio in this country is ...............

20%

The correct answer is Option (3) → 20%

Total credit created = ₹500 crores
Initial deposit (cash reserve) = ₹100 crores

The credit multiplier (K) is given by:Total Credit / Initial Deposit = 500 / 100 = 5

K = 1/Required Reserve Ratio ($\text{RRR)}$

$\text{5 = 1/Required Reserve Ratio (RRR)}$

$\text{RRR = 1/ 5 = 0.20 or 20\%}$
