Price of less grade coconut oil = Rs. $\frac{78}{\mathrm{L}}$
Price of fine grade coconut oil = Rs. $\frac{96}{\mathrm{L}}$
Quantity of fine grade coconut oil = 10 L
Final price of mixture = Rs $\frac{84}{\mathrm{L}}$
Let the quantity of low grade coconut oil be x L
By the rule of alligation, we have-Quantity of fine grade coconut oil,1 unit = 10 L
So, Quantity of low grade coconut oil, 2 unit = 20L
