oooooh... sorry sorry sorry...
change the length of HT to cm
90 km = 90 * 1000 * 100 = 9000000
and 1/n = 4.5/9000000
got it?
for such type of scales when you are not given the unit to represent on the scale, u have to keep the same unit on both sides.
4.5 cm on map represents 9000000 cm in reality. and this scale becomes applicable on ANY unit....
4.5 m on map represent 9000000 m in reality
and even 4.5 feet on map represent 9000000 feet in reality.

yes the Q says that OV = v

OL + LV = OV
OL = 2/3 of OV
LV = 1/3 of OV
2 LV = OL
Thats the exact confusion i have.. how did u managge u get 2/3? i tried so much!

its written LO is 2 times LV . so shouldnt LV be half?:S why 1/3?
