On a scale of map,0.6 cm represent 6.6 km.If the distance between the points on the map is 80.5 cm,the actual distance between these points is :	Options:	A) 9 km	B) 72.5 km	C) 190.75 km	D) 885.5 km	E) None of these
Solution   Let the actual distance be x km.Then,   More distance on the map,More is the actual distance (Direct Proportion)   ∴ 0.6 : 80.5 : : 6.6 : x ⇔ 0.6x = 80.5 × 6.6 ⇔ x = ⇔ x = 80.5x6.6/0.6=x=885.5. Answer 885.5 km
