Step-by-step explanation:
Length of 1st rope = x+20
Length of 2nd rope = x
Length of 3rd rope = x-10
According to the question,
x + 20 + x + x + (-10) = 70
x + 20 + x + x - 10 = 70
3x + 10 = 70
3x = 60
x = 20
Length of 1st rope = x+20 = 20 + 20 = 40 cm
Length of 2nd rope = x = 20 cm
Length of 3rd rope = x-10 = 20 - 10 = 10 cm
