CAT 2023 Slot 3 Solved Paper

Let the volume of mixture $\mathrm{A}$ be $200\mathrm{ml}$, which implies the quantity of cocoa in the mixture is $120\mathrm{ml}$, and the quantity of sugar $\ln$ the mixture $80\mathrm{ml}$.
Similarly, let the volume of the mixture be $300\mathrm{ml}$, which implies the quantity of coffee, and sugar in the mixture is 210 , and $90\mathrm{ml}$, respectively.
Now we combine mixture $\mathit{A}$, and $\mathit{B}$ in the ratio of $2:3$ (if $200\mathrm{ml}$ mixture $\mathit{A}$, then $300\mathrm{ml}$ of mixture $\mathit{B}$ ).
Hence, the volume of the mixture $\mathit{C}$ is $\left(200+300\right)=500\mathrm{ml}$, and the quantity of the sugar is $\left(90+80\right)=170\mathrm{ml}$.
Now he mixes $\mathrm{C}$ with an equal amount of milk to make a drink, which implies the quantity of the final mixture is $\left(500+500\right)=1000\mathrm{ml}$
The quantity of sugar in the final mixture is $170\mathrm{ml}$.
Hence, the percentage is $17\%$
The correct option is A
