Question

1000 bananas weigh 141.7 kg. How much does each banana weigh? (Assume all the bananas are of equal weight).

Answer 1

Hint: Use the elementary unitary method to find the value of how much per banana weigh, also change the kilogram into grams which is \[{\bf{1kg}} = {\bf{1000g}}\] by using this relation we will get the total weight in grams.

Complete step-by-step answer:
First of all convert the total weight of bananas in grams
We know \[{\bf{1kg}} = {\bf{1000g}}\]
Which means that
\[\begin{array}{l}
\therefore 141.7kg = 141.7 \times 1000g\\
 \Rightarrow 141.7kg = 141700g
\end{array}\]
Now By applying unitary method we can say that
If the weight of 1000 bananas is 141700 g
Then the weight of one banana is \[\dfrac{{141700}}{{1000}}g\]
Which means that the weight per banana is 141.7 grams only

Note: While doing unitary method we could not have multiplied the 1000 while trying to get the total weight in grams instead we could have just left it as like \[141.7 \times 1000g\] and then while dividing it with 1000 the 1000 from denominator and numerator would have cut and we could have our correct answer without any real calculation.
