Ans 2: (Master Answer)
(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
