Question 1 of 10
1. Question
The total of the ages of Amar, Akbar and Anthony is 80 years. What was the total of their ages three years ago ?
Correct
Explanation :
Required sum = (80 – 3 x 3) years = (80 – 9) years = 71 years.Incorrect
Explanation :
Required sum = (80 – 3 x 3) years = (80 – 9) years = 71 years. 
Question 2 of 10
2. Question
A pineapple costs Rs. 7 each. A watermelon costs Rs. 5 each. X spends Rs. 38 on these fruits. The number of pineapples purchased is
Correct
EXplanation:
Let the number of pineapples and watermelons be x and y respectively.Then, 7x+5y=38 or 5y=(387x) or y=
Clearly, yis a whole number, only when (387x) is divisible by 5.
This happen when x=4.

Question 3 of 10
3. Question
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 oneeleventh of their sum.” The woman’s age is
Correct
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)
(9y9x) = (1/11)(11y + 11x) = (x + y) 10x = 8y x = (4/5)y
Clearly, y should be a singledigit multiple of 5, which is 5.
So, x = 4, y = 5.
Hence, woman’s age = 10x + y = 45 years.
Incorrect
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)
(9y9x) = (1/11)(11y + 11x) = (x + y) 10x = 8y x = (4/5)y
Clearly, y should be a singledigit multiple of 5, which is 5.
So, x = 4, y = 5.
Hence, woman’s age = 10x + y = 45 years.

Question 4 of 10
4. Question
What is the product of all the numbers in the dial of a telephone ?
Correct
Explanation :
Since one of the numbers on the dial of a telephone is zero, so the product of all the numbers on it is 0.Incorrect
Explanation :
Since one of the numbers on the dial of a telephone is zero, so the product of all the numbers on it is 0. 
Question 5 of 10
5. Question
A is 3 years older to B and 3 years younger to C, while B and D are twins. How many years older is C to D?
Correct
Explanation : Since B and D are twins, so B = D.
Now, A = B + 3 and A = C – 3.
Thus, B + 3 = C – 3 D + 3 = C3 C – D = 6.
Incorrect
Explanation : Since B and D are twins, so B = D.
Now, A = B + 3 and A = C – 3.
Thus, B + 3 = C – 3 D + 3 = C3 C – D = 6.

Question 6 of 10
6. Question
12 year old Manick is three times as old as his brother Rahul. How old will Manick be when he is twice as old as Rahul ?
Correct
Explanation :
Manick’s present age = 12 years, Rahul’s present age = 4 years.Let Manick be twice as old as Rahul after x years from now.
Then, 12 + x = 2 (4 + x) 12 + x = 8 + 2x x = 4.
Hence, Manick’s required age = 12 + x = 16 years.
Incorrect
Explanation :
Manick’s present age = 12 years, Rahul’s present age = 4 years.Let Manick be twice as old as Rahul after x years from now.
Then, 12 + x = 2 (4 + x) 12 + x = 8 + 2x x = 4.
Hence, Manick’s required age = 12 + x = 16 years.

Question 7 of 10
7. Question
There are deer and peacocks in a zoo. By counting heads they are 80. The number of their legs is 200. How many peacocks are there ?
Correct
Explanation:
Let x and y be the number of deer and peacocks in the zoo respectively. Then,x + y = 80 …(i) and
4x + 2y = 200 or 2x + y = 100 …(ii)
Solving (i) and (ii), we get) x = 20, y = 60.
Incorrect

Question 8 of 10
8. Question
A father is now three times as old as his son. Five years back, he was four times as old as his son. The age of the son (in years) is
Correct
Explanation:
Let son’s age be x years. Then, father’s age = (3x) years.Five years ago, father’s age = (3x – 5) years and son’s age = (x – 5) years.
So, 3x – 5 = 4 (x – 5) 3x – 5 = 4x – 20 x = 15.
Incorrect
Explanation:
Let son’s age be x years. Then, father’s age = (3x) years.Five years ago, father’s age = (3x – 5) years and son’s age = (x – 5) years.
So, 3x – 5 = 4 (x – 5) 3x – 5 = 4x – 20 x = 15.

9. Question
If you write down all the numbers from 1 to 100, then how many times do you write 3 ?
Correct
Explantion :
Clearly, from 1 to 100, there are ten numbers with 3 as the unit’s digit 3, 13, 23, 33, 43, 53, 63, 73, 83, 93; and ten numbers with 3 as the ten’s digit – 30, 31, 32, 33, 34, 35, 36, 37, 38, 39.So, required number = 10 + 10 = 20.
Incorrect
Explantion :
Clearly, from 1 to 100, there are ten numbers with 3 as the unit’s digit 3, 13, 23, 33, 43, 53, 63, 73, 83, 93; and ten numbers with 3 as the ten’s digit – 30, 31, 32, 33, 34, 35, 36, 37, 38, 39.So, required number = 10 + 10 = 20.

Question 10 of 10
10. Question
Today is Varun’s birthday. One year, from today he will be twice as old as he was 12 years ago. How old is Varun today ?
Correct
Let Varan’s age today = x years.
Then, Varan’s age after 1 year = (x + 1) years.
Therefore x + 1 = 2 (x – 12) x + 1 = 2x – 24 x = 25.
Incorrect
Let Varan’s age today = x years.
Then, Varan’s age after 1 year = (x + 1) years.
Therefore x + 1 = 2 (x – 12) x + 1 = 2x – 24 x = 25.
