4-1.5 = 2.5 m reading reading.
And slope is 1/10,
Then the sight on the slope is 2.5 * 10=25m,
According to the question, 45 is the correct answer.

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.

Calculations:
Given,
Height of instrument (HI) = 1.5 m.
Length of staff = 4 m.
Ground slope (downslope) = 1/10.
x = 25 m.
Given,
Height of instrument (HI) = 1.5 m.
Length of staff = 4 m.
Ground slope (downslope) = 1/10.
x = 25 m.

Sameer Sopori, You didn't have just memorized but have learned in-depth. You are 1000% percent right.

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.

Slope= h^2/2L.
h = (1.5)+4\10 = 1.9.
= 1.9^2/2*4 = 45.
h = (1.5)+4\10 = 1.9.
= 1.9^2/2*4 = 45.

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

I also agree with you @Amitkumar, it should be 15m.

What is the formula for sight on the down slope?

Yes, 15m is the right answer. I agree with it.
