Answer:
B , D
Step-by-step explanation:
Real interest rate is the interest rate adjusted for inflation rate.
Real Interest rate = Nominal Interest rate - Inflation
= 50% - 112% = -62% {Its negative}
So, such high negative real interest rate implies loss in value of held money. Hence, John lost his savings as real interest rate is negative.
Also, such higher inflation rate implies lower purchasing power of money.
So, John must have not been able to purchase the same, as much as last month - due to inflation.
