Option 1 : if the data given in statement I alone is sufficient to answer the question whereas the data given in statement II alone is not sufficient to answer the question.

Statement I:

[ alt="DS October 2018 20 solutions R Hindirev images Q12a" src="//storage.googleapis.com/tb-img/production/19/02/DS_October_2018_20_solutions_R_Hindirev_images_Q12a.PNG" style="width: 428px; height: 71px;">

[ height="18" src="file:///C:/Users/UMESHK~1/AppData/Local/Temp/msohtmlclip1/01/clip_image001.png" width="2">Ashu and Manoj will meet for the first time at C which is 300 m from B as Ashu will cover 500m as the ratio of their speed is 5 ∶ 3

Now Manoj will change his direction and run towards B and Ashu will return towards A after reaching B and meet Manoj at D

⇒ (CB + BD) /CD = (300 + x) / (300 – x) = 5/3

⇒ 3(300 + x) = 5(300 – x)

⇒ 900 + 3x = 1500 – 5x

⇒ 8x = 600

⇒ x = 75 m

Manoj again will change his direction, and both will start running towards A to reach A and Ashu has to cover 725 m.

⇒ In same time Manoj will cover 725 × 3/5 = 435 m

⇒ When Ashu reaches A, Manoj will be 75 + 435 = 510 m from B

Statement (2): Case not possible

∴ Data given in statement I alone is sufficient to answer the question whereas the data given in statement II alone is not sufficient to answer the question

The question below is followed by three statements I, II, and III. You have to determine whether the data given is sufficient for answering the question. You should use the data and your knowledge of mathematics to choose the best possible answer. A car travels from city P to city Q in T hours with a speed of v km per hour. Distance between cities P and Q is D kilometers. If it increases its speed by 5 kmph it saves some time. Find the actual speed of the car. Statement I: If the car travels from P to Q with its actual speed of v kmph and come back with the speed of v + 5 kmph in 2T – 0.6 hrs Statement II: A bus start form Q at the same time when the car starts from P and the speed of the bus is 50% more than the speed of the car and the bus meets car after covering 60% of the distance Statement III: Distance between PQ is given by D2 – 25D + 200 = 0  ?
