ক)
The statement I alone is sufficient to answer the question but the statement II alone is not sufficientখ)
The statement II alone is sufficient to answer the question but the statement I alone is not sufficientগ)
Both statements I and II together are needed to answer the questionঘ)
Either to statement I alone or statement II alone is sufficient to answer the questionঙ)
You cannot get the answer from the statement I and II together but need even more dataExplanation
Let the digit at unit place of the two digit number be x and that at ten’s place be y. From statement I, ⇒ x – y = 2 This relation can be true for many two digits number, like 13, 24, 35………… ∴ The statement I alone is not sufficient to answer the question From statement II, x + y = 8 This relation can be true for many two digits number, like 17, 28, ….. ∴ The statement II alone is not sufficient to answer the question Combining I and II, x – y = 2 x + y = 8 On solving these two relations, we get x = 5 and y = 3 Thus, number is 35. ∴ Both statements I and II together are needed to answer the questionRelated questions
