Explanation:

This can be solved using the density formula; i.e.,
#m=rhoxxV#
where:#m="mass expressed in g"#
#rho="density expressed in g/ml"#
#V="volume expressed in mL"# 
Assuming that the liquids are miscible, the mass of the liquids in the flask is computed as follows:
#m_t=mLiquid_A+mLiquid_B#
#m_t=((rho_A)(V_A)+(rho_B)(V_B))#
#m_t=((1.44g)/cancel(ml)xx25cancel(ml))+((1.48g)/cancel(ml)xx25cancel(ml))#
#m_t=36g+37g#
#m_t=73g#
