Question

a glass full of of juice weighs 1kg and half full wergh 3/4 th of a kg . what is the weight of the glass.

Answer 1

Heya friend

# Weight of glass is 1/2 kg (0.5) = 500 gram

# Weight of juice is 1/2 kg (0.5) = 500 gram

(So when glass and juice together 500gm(glass) + 500gm(juice) = 1 kg)

(And in second case glass and half juice together is 3/4 of 1 kg)

500gm(glass) + 250gm(juice) = 750 gm

(1 kg = 1000 gram)

the weight of the glass is 750 gm .

i hope it helps , plz mark as brainlest

Answer 2

weight of glass(wg) + weight of juice(wj) is 1 kg or 1000 kg

so, wg + wj = 1000...........(1)

half full of juice in glass is 3/4 of 1 kg

so, weight of glass + weight of half of juice is (3/4) 1 kg or (3/4)*1000 = 3*250 = 750 g

so, wg + (wj/2) = 750........(2)

equate (1) and (2),

wg - wg + wj - (wj/2) = 1000 -750

(2wj - wj )/2 = 250
wj = 500gm

so weight of juice is 500gm

then substitute wj in (1)

wg + wj = 1000
wg + 500 = 1000
wg = 1000 - 500
wg = 500

so weight of glass is 500 gram
