(C): Weight of 2 cylinders and 1 cone = 500g

Weight of 4 cylinders and 3 cones = 1300g

⇒ Weight of ( 2 cylinders and 1 cone  + 2 cylinders and 1 cone  + 1 cone )  = 1300g
⇒ 500g + 500g + Weight of 1 cone  = 1300g

⇒  Weight of 1 cone  = 1300 g - 1000 g = 300 g

Also,

Weight of 2 cylinders and 1 cone = 500g

⇒ 300 g + Weight of 2 cylinders  = 500 g

⇒ Weight of 2 cylinders = 500g - 300 g = 200 g

⇒ Weight of 1 cylinder = 200 / 2 = 100 g

It says that X CANNOT be subtracted from L which is wrong as X - L is meaningful and forms XL (40). So (c) is the answer.

X can be subtracted from L and that makes it 40. Please review
