Two persons, A and B, started Raman and Mohan start simultaneously from village Jawal t Dashara, with their respective speed in the ratio 3 2. After simultaneously from P towards Q. The speed travelling one-forth of the total distance, Mohan triples his of B is one sixth more than that of A. As speed and travels for some time, following which, he again soon as B reached Q, he turned back and on canges his speed and completes the rest of the journey, If both Raman and Mohan reach the village Dashara at the his way towards P, met A at R. Find the same time, and the time for which Mohan travelled at thrice distance PQ in km, if the distance PR is 72his initial speed was one-third of his total time of travel, then find the ratio of the respective time for Raman to complete entire journey and Mohan to complete last part of his km a. 52 b. 78 c. 80 d. 85 journey a. 25: 8 b. 24:7 C. 24:5 d. 28:9 Three dog D1, D2, and D3 had to run a race.
