If the actual observed value of standard penetration resistance, N is greater than 15 in a fine sand layer below water table, then the equivalent penetration resistance will be
1
\(15 + \left( {\frac{{N - 15}}{2}} \right)\)
2
\(15 + \left( {\frac{{N + 15}}{2}} \right)\)
3
\(15 - \left( {\frac{{N + 15}}{2}} \right)\)
4
cannot be determined with available data
