Question

Sujata bought a watermelon weighing 4.25 kg and gave 1 kg 750g to the children in her neighbourhood. How much of it does she have left?

Answer 1

Total weight of the watermelon = 4.25 kg

Weight of the watermelon given to the children = 1 kg 750 g = 1 kg + 750 g = 1 kg + $\frac{750}{1000}$ kg = 1 kg + 0.75 kg = 1.75 kg

∴ Weight of the watermelon left with her

= Total weight of the watermelon − Weight of the watermelon given to the children

= 4.25 kg − 1.75 kg

= 2.5 kg


$\begin{array}{ccccc}& {}^3\cancel{4}& .& {}^{12}\cancel{2}& 5\\ -& 1& .& 7& 5\\ & 2& .& 5& 0\\ & & & & \end{array}$
Thus, the weight of watermelon left with Sujata is 2.5 kg.
