Question

Anil weighed three packages on a scale. Individually, they weigh 4.2 kg, 2370 g, and 0.45 kg. Is the total weight of the packages more than or less than 7 kg?

Answer 1

$$\begin{gathered} \sin ce,1gm=\frac{1}{1000}kg \\ Totalweightofthreepackage=4.2+\left(\frac{2370}{1000}\right)+0.45 \\ =4.200+2.370+0.450 \\ =7.02kg \\ therefore,7.02>7 \\ Hence,theweightofthreepackagesismorethan7kg. \end{gathered}$$
