 Hi and welcome to the session. Let us discuss the quarrying question. The question says which of the quarrying beggars die on the same base and between the same parallels. In such a case, write the common base and the two parallels. This is the fourth figure given to us. Let's now begin with the solution. Now consider the triangle rpq and parallelogram a, b, c, t. Now base of Triangle rpq is p2 and base of parallelogram a, b, c, d is b, c. Therefore it implies that both the figures that is parallelogram a, b, c, d and Triangle rpq do not common base. Hence we can conclude that both the figures does not lie on the same base and between the same parallelograms. This is our required answer. So this completes the session. Bye and take care.
