Question

a man whose weight is 90kgs weight 25kg on the moon what will be the weight of a man whose weight is 60 kg?

​

Answer 1

Answer:

90kg man weights 25 kg on moon

then 1 kg will weight 25/90 kg on moon

so, 60 kg man will weight 25/90 ×60 kg

=1500/90 kg

=50/3 kg

=16⅔ kg

Answer 2

As per the data given in the question,

We have to determine the weight of a man on moon whose weight is 60 kg on moon, if the whose weight is 90 kgs weight 25 kg on the moon.

So, finding the weight of man, first we will find out that in what proportion does the weight of man gets differs on moon as compared on earth.

So, weight of man on earth = 90 Kg

Weight of man on moon = 25 Kg

Hence, required proportion will be,

$\frac{Weight\:on\:earth}{Weight\:on\:Earth} = \frac{90}{25} = \frac{18}{5}$

So, if the weight of man on earth = 60 Kg.

Then his weight on moon is " x" Kg.

So,

$\frac{Weight\:on\:earth}{Weight\:on\:Earth} = \frac{18}{5}\\=>\frac{60}{x} = \frac{18}{5}\\=> x=\frac{60\times 5}{18}\:Kg\\=> 16.67\:kg = 16\frac{2}{3}\:Kg$

Hence, the weight of man on moon will be 16.67 Kg, if his weight on earth is 60 Kg.
