Question

Find the sum by suitable arrangements:

$273+512+627+388$

Answer 1

Given $273+512+627+388$

To find the sum by suitable arrangement

By rearrangement, we consider $(273+627)+(512+388)$

$$\begin{gathered} \therefore (273+627)+(512+388) \\ =900+900 \\ =1800 \end{gathered}$$

Hence, $273+512+627+388$ is $1800$.
