Solution

The correct option is A 500 g
Let the unknown weight be $x k g$
Given that,
$weight of rice = 1 kg = 1000 g$
$weight of rice+unknown weight = 1.5 k g = 1500 g$
$\Rightarrow x + 1000 g = 1500 g$
$\Rightarrow x = (1500 - 1000) g = 500 g$
$So, unknown weight = 500 g$

The correct option is A 500 gLet the unknown weight be x kg Given that, weight of rice = 1 kg = 1000 g weight of rice+unknown weight=1.5 kg =1500 g ⇒x+1000 g=1500 g ⇒x=(1500−1000)g=500 g So, unknown weight = 500 g
