$5:2:3$
$1:5:5$
$\mathit{–}\mathit{–}\mathit{–}\mathit{–}\mathit{–}\mathit{–}\mathit{–}$
$5:10:15\Rightarrow 1:2:3$
Now, CP of rasgulla $=120\times \frac{3}{4}=\mathrm{Rs}90$
∴ Ratio of amounts invested in a kg of rasgulla will be
$15:30:45$
But clearly we can see from the quantity ratio, Sugar weight in a kg of Rasgulla $=\frac{5}{10}=\frac{1}{2}$kg
So, $\frac{1}{2}$kg price of sugar = Rs 15
⇒ 1 kg price of sugar = Rs 30
