7. | A woman says, "If you reverse my own age, the figures represent my husband's age. He is, of course, senior to me and the difference between our ages is one-eleventh of their sum." The woman's age is |
|||||||

Answer: Option C Explanation: Let x and y be the ten's and unit's digits respectively of the numeral denoting the woman's age. Then, woman's age = (10X + y) years; husband's age = (10y + x) years. Therefore (10y + x)- (10X + y) = (1/11) (10y + x + 10x + y) (9y-9x) = (1/11)(11y + 11x) = (x + y) 10x = 8y x = (4/5)y Clearly, y should be a single-digit multiple of 5, which is 5. So, x = 4, y = 5. Hence, woman's age = 10x + y = 45 years. |

8. | A girl counted in the following way on the fingers of her left hand : She started by calling the thumb 1, the index finger 2, middle finger 3, ring finger 4, little finger 5 and then reversed direction calling the ring finger 6, middle finger 7 and so on. She counted upto 1994. She ended counting on which finger ? |
|||||||

Answer: Option B Explanation: Clearly, while counting, the numbers associated to the thumb will be : 1, 9,17, 25,..... i.e. numbers of the form (8n + 1). Since 1994 = 249 x 8 + 2, so 1993 shall correspond to the thumb and 1994 to the index finger. |

9. | A man has Rs. 480 in the denominations of one-rupee notes, five-rupee notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has ? |
|||||||

Answer: Option D Explanation: Let number of notes of each denomination be x. Then, x + 5x + 10x = 480 16x = 480 x = 30. Hence, total number of notes = 3x = 90. |

10. | What is the product of all the numbers in the dial of a telephone ? |
|||||||
