Question

the weight of a glass bowl and the marbles it contains is 50 gram . if the marbles in the given bowl are doubled , the total weight of the bowl and the marbles becomes 92 grams . given that each of the marble has same weight , find the weight of the bowl.

Answer 1

let wt of glass bowl =x wt of marbles = y
so x+y = 50g .....(1)
marbles doubled => so wt of marbles =2y
new wt bowl + marbles = x+ 2y
so x+ 2y = 92 g .....(2)

so by (1 ) and (2) ... y = 42 g
thus x = 8 g
so wt of bowl = 8 g ~@lice
