Question 163

Mr. Mendel grew one hundred flowering plants from black seeds and white seeds, each seed giving rise to one plant. A plant gives flowers of only one colour. From a black seed comes a plant giving red or blue flowers. From a white seed comes a plant giving red or white flowers. How many black seeds were used by Mr. Mendel?

A. The number of plants with white flowers was 10.

B. The number of plants with red flowers was 70.

Solution

Using only statement A, we can say that at least 10 white seeds were used. But we cannot find the exact number.

Using only statement B, we cannot make any inference.

Using both the statements, we can only make the same conclusion as we made using statement A.

Hence, the question cannot be answered by using both the statements together.
