7.5 kg think so.I am not sure perfectly but I think this is right.

spillutla: Yes. It is 7.5 in magnitude, but I would not have used the unit 'kilograms' as it is a unit of mass, and mass doesn't change anywhere In this universe, except if you are traveling close to the speed of light. A better unit would be newton, as it is a unit of weight (weight is a force - that is the gravitational force on a body) and weight can change from place to place.
svdrenu: sorry 7.5N
spillutla: No.. I DIDN'T say 7.5 N was RIGHT. But I said 7.5 kg was WRONG.

Firstly, I would like to point out an error. The unit kilograms is used only for mass, and not for weight. And as mass doesn't change anywhere in this universe (unless you are moving close to the speed of light) I will refrain from taking kilograms as the unit, but will take newtons (N) (a unit of weight) as the unit, as weight depends on the gravitational pull, a force, and changes from place to place.
Given ratio =
78:13 = 6:1
Now, ratio of Anand's weight on earth to Anand's weight on moon =
45:x (taking his weight on moon as x)
So, they will be in proportion (ratios will be same)
45:x: :6:1
Multiplying the means and extremes, we get
45×1 = 6×x
Rearranging, we now have
x = 45/6 = 7.5N
Therefore, he weighs 7.5N on moon.

Hope you liked the answer! Please mark my answer as brainliest! Thanks!
