U
Thank you sir. I did the same question earlier, but was not able to figure out clues. You explained it quite well. Sir, you said that 15 down and 15 across means words start with same alphabet. So, that means always 2 words start with same alphabet or there can be more?? and 14 down and 14 across also means the same?
Sir why did you took total time as t and also the total distance as 3t?
SIR HERE TOTAL DISTANCE =3T (SPPED OF JAMAL * TOTAL TIME) D=3T ASSUME A BE THE REMAINING TIME NOW 3T=D/4 +6(T/3) +2A PUT D=3T AND SOLVE YOU GET 8:1
Sir, In the Ram Mohan ques., I didn't get the point that why u took t/3. In the ques. its given that the distance in which mohan triples its speed that should be t/3 then why u consider it as another time.
WHAT WRONG IN THAT

2. 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. The A bee, when flying at its normal speed, takes 25 distance covered by 2 steps of D1, 3 steps of D2min 12 sec more to travel 3.15 km against the wind and 5 steps of D3 are all equal. Also time taken by than the time it takes to travel the same distance D1 to take 4 steps, D2 takes 3 steps and D3 takesalong the direction of the wind. If it doubles its 6 steps all equal. What is the ratio of speeds ofspeed and travel the same distance, it takes 6 min walking of D1, D2 and D3 respectively? a. 10: 5 12 c. 10: 5:6 less when it flies along the direction of wind than it takes to fly against the wind.
