SSC CHSL 30th May 2022 Shift-2

- Let's determine how much of each type of rice is mixed.

- Let "x" be the weight in kg of the Rs40 per kg rice.

- Let "y" be the weight in kg of the Rs47.50 per kg rice.

- The total weight of the rice blend is given as 15 kg:

\[ x + y = 15 \]

- The total cost of the blended rice is Rs645:

\[ 40x + 47.5y = 645 \]

- Solving these equations:

- From \( x + y = 15 \), we get \( x = 15 - y \).

- Substituting in the cost equation:

\[ 40(15 - y) + 47.5y = 645 \]

- Simplifying gives \( 600 - 40y + 47.5y = 645 \).

- Which simplifies to \( 7.5y = 45 \).

- Thus, \( y = 6 \) kg, which is the weight of the Rs47.50 per kg rice.

- Option:2, 6 is the correct answer .
