The given equations are solved on the basis of a certain system. On the same basis, find out the correct answer from amongst the options.
If 12 - 5 = 84, 10 - 5 = 50, 8 - 5 = 24, then 6 - 5 = ?
it shoould be b=30
A body immersed in a fluid experiences an upward thrust which depends on
(A) The weight of the fluid displaced by it
(B) The volume of the body

(D) All of these.
I THINK THE ANSWER SHOULD BE C BECAUSE IT IS MASS OF THE BODY WHICH IS IMMERSED IN WATER AND THE WEIGHT OF THE BODY IS MORE THAT'S OF THE FLUID THAT'S WHY IT EXPERIENCES UPWARD THRUST
