Slope = 1/10,
H.I = 1/2 = 0.5,
Sight = (0.5 + 4)/1 ÷ 10 = 45.
H.I = 1/2 = 0.5,
Sight = (0.5 + 4)/1 ÷ 10 = 45.

@Sameer Sopori.
How 15 + 25=45?
How 15 + 25=45?

Sight = (4-1. 5) / (1/10).
= 35m.
Since sight is 35m the sight on the up slope should be less than 45m So, option C is the correct.
= 35m.
Since sight is 35m the sight on the up slope should be less than 45m So, option C is the correct.

Instrument height is 1/2.
Then 4+0.5=4.5.
4.5*10=45
Then 4+0.5=4.5.
4.5*10=45

Grading is 1:10 which is upwards and instrument height is 1.5m so 1.5*10=15m, ie only horizontal 15m is possible for zero staff reading.
And the Answer must be 15m.
And the Answer must be 15m.
