20488. The value of representative fraction of a map is 1: 10000 then what is the measurement in map for actual distance 500m? [MOD-20]
5m
5cm
5mm
5in
10000 cm represents = 1cm 50000 (500x100)cm represents = 10000 cm = 5cm
20489. For a traverse containing 10 sides, what would be the correction applied for the first side, if it consists a closing error of + 1.92? [BB-20]
19.0
19.2
1.902
0.192
The correction for sides in a traverse is given as correction = e/N, where N is the number of sides and e is the closing error. On substitution, we get, correction = 1.92/10 = 0.192.
