    Solution

    Let the number of marbles with ‘Ankit’, ‘Bhavya’, and ‘Chetan’ be ‘x’, ‘y’, and ‘z’, respectively. Therefore, x+y=z+25 ………(1) y+z=x+15 ………(2) x+z=60 ………(3) Add equations (1), (2), and (3): 2(x+y+z)=x+z+100 Or, 2(x+y+z)=60+100 Or, x+y+z=160/2=80 Thus, the total number of marbles with Ankit, Bhavya, and Chetan together is 80.
