Option 1 : Statement 1 alone is sufficient to answer the question, but statement 2 alone is not  sufficient.

Let M = BUNTY's age right now,

 B = CHINTU's age right now. Question gives us the equation M = B + 15. 

USING THE STATEMENT I:

It gives us a second equation, (M + 3) = 1.5 × (B + 3)

 With this equation and the equation calculated by question, we have two equations with two unknowns, so we can solve for the values of M & B

(M + 3) = 1.5 × (B + 3)

 M + 3 = 1.5B + 4.5

M – 1.5B = 1.5       ….(1)

M = B + 15

M – B = 15       ….(2)

Solving 1 and 2, we get

B = 27 and M = 42

This statement, alone and by itself, is sufficient

USING THE STATEMENT II

If BUNTY is 15 years older than CHINTU, then when BUNTY was 25, CHINTU would have had to have been 10. 

We are given absolutely no indication when these people were these ages, so this doesn't help us at all.

This statement, alone and by itself, is not sufficient

Correct Answer is (1), Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient

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  ?
