  We investigate the effect of repulsive interaction between hadrons on the
susceptibilities of conserved charges, namely baryon number (B), electric
charge (Q) and strangeness (S). We estimate second and fourth-order
susceptibilities of conserved charges, their differences, ratios and
correlations within the ambit of the mean-field hadron resonance gas (MFHRG)
model. We consider repulsive mean-field interaction among meson pairs,
anti-meson pairs, baryon pairs and anti-baryon pairs separately and constrain
them by confronting MFHRG results of various susceptibilities with the recent
lattice QCD (LQCD) data. We find that the repulsive interactions between
baryon-baryon pairs and antibaryon-antibaryon pairs are sufficient to describe
the thermodynamics of hadronic matter at temperatures below the QCD transition
temperature. Very weak mesonic repulsive interaction is needed only to describe
electric charge susceptibilities and can be neglected in the description of
other susceptibilities. We finally conclude that the repulsive interaction
between hadrons plays a very important role in describing the thermodynamic
properties of hadronic matter, especially near quark-hadron phase transition
temperature ($T_c$). The mean-field parameter for baryons ($K_B$) should be
constrained to the range $0.40\le K_B\le 0.450$ $\text{GeV.fm}^{3}$ to get a
good agreement with the LQCD results.
