Number of such number =14
∴ Required percentage = | ❨ | 14 | x 100 | ❩% = 20%. |
70 |
∴ Valid votes polled by other candidate = 45% of 6000
= | ❨ | 45 | x 6000 | ❩ | = 2700. |
100 |
5% of A + 4% of B = | 2 | (6% of A + 8% of B) |
3 |
⟹ | 5 | A + | 4 | B | = | 2 | ❨ | 6 | A + | 8 | B | ❩ |
100 | 100 | 3 | 100 | 100 |
⟹ | 1 | A + | 1 | B | = | 1 | A + | 4 | B |
20 | 25 | 25 | 75 |
⟹ | ❨ | 1 | - | 1 | ❩ A = | ❨ | 4 | - | 1 | ❩ B |
20 | 25 | 75 | 25 |
⟹ | 1 | A = | 1 | B |
100 | 75 |
A | = | 100 | = | 4 | . |
B | 75 | 3 |
∴ Required ratio = 4 : 3
Then, 6% of x = | 30 |
100 |
⟹ x = | ❨ | 30 | x | 100 | ❩ = 5. |
100 | 6 |
∴ Cost of tax free items = Rs. [25 - (5 + 0.30)] = Rs. 19.70
Then, error = | 5 | x - | 3 | x = | 16 | x. |
3 | 5 | 15 |
Error% = | ❨ | 16x | x | 3 | x 100 | ❩% = 64%. |
15 | 5x |
= 110 - (60)
= 50.
∴ Required percentage = | ❨ | 50 | x 100 | ❩% = 45 | 5 | % |
110 | 11 |
Then, z + 120% of z = 550.
⟹ z + | 120 | z = 550 |
100 |
⟹ | 11 | z = 550 |
5 |
⟹ z = | ❨ | 550 x 5 | ❩ = 250. |
11 |
Then, x + 9 = | 56 | (x + 9 + x) |
100 |
⟹ 25(x + 9) = 14(2x + 9)
⟹ 3x = 99
⟹ x = 33
So, their marks are 42 and 33.
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
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. |
