In the question, a question statement is given, followed by two statements, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given statement, if any, is sufficient to answer the question statement. Question statement : The average income of Leena, Meena and Kishore is Rs 45,000. What is the income of Leena? Statement 1 : Leena earns twice as much as Meena. Statement 2 : Meena and Kishore earn the same amount. Correct Answer Both I and II have to be taken together to be sufficient
The given statement: The average income of Leena, Meena and Kishore is Rs 45,000.
Total income of Leena, Meena and Kishore = 45000 × 3 = Rs. 1,35,000
Let the incomes of Leena be L, Meena be M, and Kishore be K.
Then according to statement 1,
L = 2M (i)
According to statement 2,
M = K (ii)
If we combine both the statements, we get:
L = 2M and L = 2K
⇒ M = L/2
⇒ K = L/2
According to the data given in the statement, we get:
L + L/2 + L/2 = Rs. 1,35,000
2L = Rs.1,35,000
L = Rs. 67,500
Thus, Leena earns Rs. 67500.
Hence, "both statements are needed to get the answer".
