In what ratio must rice at ₹45 per kg is mixed with rice ₹60 per kg so that the mixture by worth ₹54 per kg ?

2 : 3

The correct answer is option (1) : 2 : 3

c= ₹45 per kg

d= ₹60 per kg

m= ₹54 per kg

$\frac{\text{quantity of cheaper rice}}{\text{quantity of dearer rice}}$

$=\frac{60-54}{54-45}=\frac{6}{9}=\frac{2}{3}$

Hence, the required ratio $= 2: 3$
