Hint: The terms "mass" and "weight" are used interchangeably in ordinary conversation, but the 2 words don't mean an equivalent thing. The difference between mass and weight is that mass is the amount of matter during a material, while weight may be a measure of how the force of gravity acts upon that mass.

Complete step-by-step solution:
A weighing balance measures the load of a body and is calibrated to point out the mass. Once we stand on a weighing balance, our weight acts downwards while upthrust because air acts upwards. Because of the upthrust, the body appears to gain some weight. As a result, our apparent weight becomes the truth weight.
As a result, the body gets pushed slightly upwards, causing the weighing balance to display a reading less than the actual value. This upward force is called the buoyant force. Thus, the weighing balance measures the apparent weight, which is less than the true weight.
When the apparent weight is measured by the weighing machine, the mass indicated by it is less than the actual mass. So, the actual mass will be more than \[42kg\].

Note:While an individual's mass doesn't change elsewhere within the system, the acceleration thanks to gravity and weight varies dramatically. The calculation of gravity on other bodies, as on Earth, depends not only on mass but also on how far the surface is from the middle of gravity. On Earth, for example, your weight is slightly lower on a mountain top than on a stumped level. The effect becomes even more dramatic for giant bodies, like Jupiter.
While the gravity exerted by Jupiter thanks to its mass is \[316\] times greater than that of Earth, you would not weigh \[316\] times more because its "surface" (or the cloud level we call the surface) is thus far out from the middle.
