Statement: A fund promises of doubling the investor's money in one year. 
Assumption:
I. People are looking to grow their wealth. 
II. The fund is a scam.

Detailed Solution for RRB Group D Mock Test - 38 - Question 91

Only if people are looking to grow their wealth that the fund is in operation. Thus, assumption I is implicit. 
We cannot assume that the fund is a scam on the basis of the promise they made. Thus, assumption II is not implicit. 
Hence, option A is the right answer.

RRB Group D Mock Test - 38 - Question 92

In the question below a statement is followed by two assumptions numbered I and II. An assumption is something supposed or taken in for granted. You have to consider the statement and the following assumptions and then decide which of the assumptions is implicit in the statement.

Statement: The company decided to increase the price of its products to avoid going bankrupt. 
Assumption:
I. The company feels that buyers won’t be interested in their products if the prices are increased. 
II. An increase in the price of the products will help the company increase revenue and reduce losses.

Detailed Solution for RRB Group D Mock Test - 38 - Question 92

If the buyers weren't interested in the product after price rise, the company wouldn’t implement the strategy. Thus, assumption I is not implicit. 
Since the company decided to increase the price to avoid bankruptcy, the increased price would help reduce losses to the company. Thus, assumption II is implicit. 
Hence, option B is the right answer.

RRB Group D Mock Test - 38 - Question 93

Statement 1: A is taller than B and C. E is taller than D. 
Statement 2: B is taller than D and C. E is taller than A.

Detailed Solution for RRB Group D Mock Test - 38 - Question 95

A is taller than B and C. E is taller than D. We do not have any details to compare the heights of E and A. Therefore, statement I alone is insufficient.

B is taller than D and C. E is taller than A. Again, we do not have any information to compare the heights of B and E. Therefore, statement II alone is insufficient.

Combining both the statements, we can say that B is taller than D and C. A is taller than B and E is taller than A. Therefore, E must be the tallest. We can answer the question by combining the data given in both the statements. Therefore, option C is the right answer.
