Let the length of smaller part be 'x' cm and larger part be 'y' cm.
Length of rope = 560 cm
⇒ x + y = 560
⇒ y = 560 - x eq.
Twice the length of smaller part is equal to of the larger part
⇒ 6x = y
⇒ 6x = 560 - x
⇒ 7x = 560
⇒ x = 80
Using this in eq.
⇒ y = 560 - 80 = 480
Length of smaller part = 'x' cm = 80 cm
Length of larger part = 'y' cm = 480 cm
