Question

Ram mixes $15$ kg of sugar purchased with the rate, off Rs. $8.00$ per kg with $25$ kg of sugar purchased at the rate of Rs. $10.00$ per kg. At what rate per kg should Ram sell the mixture to get a profit of $3$ per kg?

• A. Rs. $12.25$
• B. Rs. $15.75$
• C. Rs. $18.18$
• D. Rs. $19.75$

Answer 1

The correct option is A Rs. $12.25$

C.P. of $40$ kg of sugar $=$ Rs. $(15\times 8+25\times 10)=$ Rs. $120+$ Rs. $250=$ Rs. $370$
$\therefore$ C.P. of $1$ kg of sugar $=$ Rs. $\frac{370}{40}=$ Rs. $9.25$
$\therefore$ S.P. of $1$ kg of sugar $=$ Rs. $9.25+$ Rs. $3=$ Rs. $12.25$
