Option 1 : The data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

From statement I:

M is not a multiple of 2. So, M is odd. It can be written as (2k + 1).

⇒ MN = (2k + 1)N

Using binomial theorem, if N is natural number, then all terms of expansion will be multiple of 2, except 1N. So, remainder will be 1.

∴ Statement I alone is sufficient to answer the question.

From statement II:

N is not a multiple of 2. M can be even or odd. Accordingly, MN can be even or odd, irrespective of value of N. And leave different remainders when divided by 2.

∴ 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  ?
