Solution:

According to the question,
Cost price of

26 {kg}

of rice

=26 × 20

⇒ \;\text " Rs. "\; 520

Cost price of

30 {kg}

of rice

=30 × 36

⇒ \;\text " Rs. "\; 1080

Total cost price of

56 {kg}

of rice

=520+1080

⇒ \;\text " Rs. "\; 1600

Selling price of

56 {kg}

of rice

=56 × 30

⇒ \;\text " Rs. "\; 1680

Profit percent

=\{[( {SP}- {CP}) \/ {CP}] × 100\}

⇒\{[(1680-1600) \/ 1600] × 100\}
