Given $$\begin{aligned} & (85 \% \text { of } 420)+(? \% \text { of } 1080)=735 \\ & \Rightarrow\left(\frac{85 \times 420}{100}\right)+\left(\frac{(?) \times 1080}{100}\right)=735 \\ & \Rightarrow 357+\left(\frac{(?)+1080}{100}\right)=735 \\ & \Rightarrow\left(\frac{(?) \times 1080}{100}\right)=(735-357)=378 \\ & \Rightarrow(?)=\frac{378 \times 100}{1080}=35 \end{aligned}$$
