Class : Class 1
(B): Let Breadth be x and,
Length = (3/2) x
Perimeter = 2(l + b) = 120 m
2(1.5x + x) = 120
5x = 120
x = 120 ÷ 5 = 24 m
Breadth = x = 24 m
Length = 1.5 × 24 = 36 m
Area = length × breadth = 24 × 36 = 864 sq. m

(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
