OA: C

Let us assume Rasheed bought $$C$$ packages of Chocolate and $$T$$ packages of toffee.
Each package has $$2$$ Bar.
So Rasheed handed out $$\frac{2}{3}*2C$$ Chocolate bars and $$\frac{3}{5}*2T$$ toffee bars.
We have to answer "What is value of $$C$$ i.e Number of Chocolate package "

1) Rasheed bought 1 fewer package of chocolate bars than toffee bars.
$$T-C=1$$
As we cannot find the value of either $$T$$ or $$C$$ , So Statement $$1$$ alone is insufficient.

2) Rasheed handed out the same number of each kind of candy bar.
$$\frac{2}{3}*2C=\frac{3}{5}*2T$$
$$10C=9T$$
As we cannot find the value of either $$T$$ or $$C$$ , So Statement $$2$$ alone is insufficient.

Combining $$(1)$$ and $$(2)$$, we get
$$T-C=1$$....(1)
$$10C=9T; \quad T = \frac{10C}{9}$$....(2)
Putting (2) into (1), we get
$$\frac{10C}{9}-C=1$$
$$C=9$$
Combining $$(1)$$ and $$(2)$$, we can get value of $$C$$.
