Given,
⇒ X = Y + 60% of Y
⇒ X = Y + 0.6Y
⇒ X = 1.6Y
⇒ Y = (1/1.6)X
⇒ Y = 0.625X
⇒ Y = 62.5% of X
⇒ Y = X - (100 - 62.5)% of X
⇒ Y = X - 37.5% of X
∴ Y is 37.5% less than X
⇒ X = Y + 60% of Y
⇒ X = Y + 0.6Y
⇒ X = 1.6Y
⇒ Y = (1/1.6)X
⇒ Y = 0.625X
⇒ Y = 62.5% of X
⇒ Y = X - (100 - 62.5)% of X
⇒ Y = X - 37.5% of X
∴ Y is 37.5% less than X
