All pots are rings + All rings are paints = A + A = A = All pots are paints → conversion → Some paints are pots (I) Hence I follows. All bangles are rings + All rings are paints = A + A = A = All bangles are paints → implication → Some bangles are paints (I) Hence II follows.
Correct Option: E
All pots are rings + All rings are paints = A + A = A = All pots are paints → conversion → Some paints are pots (I) Hence I follows. All bangles are rings + All rings are paints = A + A = A = All bangles are paints → implication → Some bangles are paints (I) Hence II follows.

All paintings are photographs.
Some photographs are designs.

All paintings are photographs + Some photographs are designs = A + I = No conclusion Hence I does not follow. Some photographs are designs + Some designs are movies = I + I = No conclusion Hence II does not follows.
Correct Option: D
All paintings are photographs + Some photographs are designs = A + I = No conclusion Hence I does not follow. Some photographs are designs + Some designs are movies = I + I = No conclusion Hence II does not follows.

Some syrups are medicines + All medicine are powder = I + A + I = Some syrups are powders.
Hence I follow. Some tablets are capsules + All capsules are syrups = I + A + I = Some tablets are syrups → conversion → Some syrups are tablets (I). Hence II follows.Correct Option: E
Some syrups are medicines + All medicine are powder = I + A + I = Some syrups are powders.
Hence I follow. Some tablets are capsules + All capsules are syrups = I + A + I = Some tablets are syrups → conversion → Some syrups are tablets (I). Hence II follows.

All benches are cots (A) → conversion → Some cots are benches (I) Hence follows. No cot is lamp + Some lamps are candles = I + E = O* = Some candles are not cots Hence II does not follow.
Correct Option: A
All benches are cots (A) → conversion → Some cots are benches (I) Hence follows. No cot is lamp + Some lamps are candles = I + E = O* = Some candles are not cots Hence II does not follow.
