I: The ratio between the present ages of A and B is 7:10 respectively and B is 9 years elder than A. Quantity II: 25 years
AQuantity I ≥ Quantity IICorrect AnswerIncorrect Answer
BQuantity I ≤ Quantity IICorrect AnswerIncorrect Answer
CQuantity I > Quantity IICorrect AnswerIncorrect Answer
DQuantity I < Quantity IICorrect AnswerIncorrect Answer
EQuantity I = Quantity IICorrect AnswerIncorrect Answer
Solution
Quantity I: Let the present age of A and B be 7x and 10x respectively. According to question, => 10x – 7x = 9 => x = 3 A’s age after 4 years = (7 x 3) + 4 = 25 years Quantity II: 25 years Therefore, Quantity I = Quantity II
