Question: In a race of 1200 m, X can beat Y by 120 m. In a 600 m, Y beats Z by 60 m. In a race of 600 m. X will beat Z by-

Solution:
While X covers 1200 Y covers 1080
while X covers 600 Y covers 540m

While Y covers 600, Z covers 540m
While Y covers 540, Z covers (540 × 540)/600
= 486 m

∴ in a 600 m race X will beat Z by = (600 - 486) m
= 114 m
