When a specimen of M25 concrete is loaded to a stress level of 12.5 MPa, a strain of $500\times {10}^{-6}$ is recorded. If this load is allowed to stand for a long time, the strain increases to $1000\times {10}^{-6}$. In accordance with provisions of IS: 456-2000, considering the long-term effects, the effective modulus of elasticity of the concrete (in MPa) is _______.
