Correct Answer: None of these
Explanation:
| x% of y = | ❨ | x | x y | ❩ | = | ❨ | y | x x | ❩ | = y% of x |
| 100 | 100 |
∴ A = B.
Correct Answer: 100
Explanation:
Let the number of students be x . Then,
Number of students above 8 years of age = (100 - 20)% of x = 80% of x.
| ∴ 80% of x = 48 + | 2 | of 48 |
| 3 |
| ⟹ | 80 | x = 80 |
| 100 |
⟹ x = 100.
Correct Answer: 700 apples
Explanation:
Suppose originally he had x apples.
Then, (100 - 40)% of x = 420.
| ⟹ | 60 | x x = 420 |
| 100 |
| ⟹ x = | ❨ | 420 x 100 | ❩ = 700. |
| 60 |
Correct Answer: 4% of a
Explanation:
| 20% of a = b ⟹ | 20 | a = b. |
| 100 |
| ∴ b% of 20 = | ❨ | b | x 20 | ❩ | = | ❨ | 20 | a x | 1 | x 20 | ❩ | = | 4 | a = 4% of a. |
| 100 | 100 | 100 | 100 |
Correct Answer: Rs. 6876.10
Explanation:
| Rebate = 6% of Rs. 6650 = Rs. | ❨ | 6 | x 6650 | ❩ | = Rs. 399. |
| 100 |
| Sales tax = 10% of Rs. (6650 - 399) = Rs. | ❨ | 10 | x 6251 | ❩ | = Rs. 625.10 |
| 100 |
∴ Final amount = Rs. (6251 + 625.10) = Rs. 6876.10
Correct Answer: 5%
Explanation:
Increase in 10 years = (262500 - 175000) = 87500.
| Increase% = | ❨ | 87500 | x 100 | ❩% = 50%. |
| 175000 |
| ∴ Required average = | ❨ | 50 | ❩% = 5%. |

Correct Answer: Sunday
Explanation:
15 th August, 2010 = (2009 years + Period 1.1.2010 to 15.8.2010)
Odd days in 1600 years = 0
Odd days in 400 years = 0
9 years = (2 leap years + 7 ordinary years) = (2 x 2 + 7 x 1) = 11 odd days ≡ 4 odd days.
Jan. Feb. March April May June July Aug. (31 + 28 + 31 + 30 + 31 + 30 + 31 + 15) = 227 days
∴ 227 days = (32 weeks + 3 days) ≡ 3 odd days.
Total number of odd days = (0 + 0 + 4 + 3) = 7 ≡ 0 odd days.
Given day is Sunday.
Correct Answer: 8x
Explanation:
x weeks x days = (7 x + x ) days = 8 x days.
Correct Answer: Sunday
Explanation:
28 May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)
Odd days in 1600 years = 0
Odd days in 400 years = 0
5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) ≡ 6 odd days
Jan. Feb. March April May (31 + 28 + 31 + 30 + 28 ) = 148 days
∴ 148 days = (21 weeks + 1 day) ≡ 1 odd day.
Total number of odd days = (0 + 0 + 6 + 1) = 7 ≡ 0 odd day.
Given day is Sunday.
Correct Answer: Saturday
Explanation:
Each day of the week is repeated after 7 days.
So, after 63 days, it will be Monday.
∴ After 61 days, it will be Saturday.
