Let the number of rice bowl be x
Let the number of dal bowl be y
Let the number of meat bowl be z
x + y + z = 65 $........$(i)
According to question, 2x = 3y = 4z
Let 2x = 3y = 4z = k
$\mathrm{x}=\frac{\mathrm{k}}{2},\mathrm{y}=\frac{\mathrm{k}}{3},\mathrm{z}=\frac{\mathrm{k}}{4}$
⇒ $\frac{\mathrm{k}}{2}+\frac{\mathrm{k}}{3}+\frac{\mathrm{k}}{4}=65$
⇒ $\frac{6\mathrm{k}+4\mathrm{k}+3\mathrm{k}}{12}=65$
⇒ $\frac{13\mathrm{k}}{12}=65$
⇒ k = 60
