### Option Analysis

Interest Rate per month: 6%/12 months = 0.5% (monthly)

Statement I is sufficient: As of June 1 of last year, the investment had earned $200 in interest.

Sufficient: interest earned in one month

= $200 Principal∗(0.5/100)

=200

Principal amount = $40000.

Hence sufficient.

Statement II is sufficient: As of July 1 of last year, the investment had earned $401 in interest.

Sufficient: interest earned in two months = $401

Principal∗(1+0.5/100)∗(0.5/100)=401

We can solve this equation to find out the principal amount. Hence sufficient.
