The Reduced Levels (RLs) of the points P and Q are +49.600 m and +51.870 m respectively. Distance PQ is 20 m. The distance (in m from P) at which the +51.000 m contour cuts the line PQ is

- 15.00
- 12.33
- 3.52
- 2.27
- 15.00
Correct Option: B
P and O are in same line at R. L = + 49.60 m
In ∆POQ,
| sin θ = | = | = 0.1135 | ||
| PQ | 20 |
We have to find PS.
In ∆PSR
| sin θ = | = | |||
| PS | PS |
| 0.1135 = | ||
| PS |
∴ PS = 12.33 m
