This document contains information about an engineering mathematics examination, including five questions covering topics like numerical methods for solving differential equations, complex variables, orthogonal polynomials, and probability. It also provides materials data and stipulations for designing a M35 grade concrete mix according to Indian standards. The first part of the document outlines five questions on the exam covering numerical methods like Euler's method, Picard's method, Runge-Kutta method, and Milne's predictor-corrector method for solving differential equations. It also includes questions on complex variables, orthogonal polynomials, and probability. The second part provides test data for materials to be used in designing a concrete mix for M35 grade concrete according to Indian standards, including stipulations
