S.P. = 85% of Rs. 1400 = Rs. | ❨ | 85 | x 1400 | ❩ | = Rs. 1190 |
100 |
S.P. of 6 toffees = 120% of Re. 1 = Rs. | 6 |
5 |
For Rs. | 6 | , toffees sold = 6. |
5 |
For Re. 1, toffees sold = | ❨ | 6 x | 5 | ❩ | = 5. |

C.P. of 1st transistor = Rs. | ❨ | 100 | x 840 | ❩ | = Rs. 700. |
120 |
C.P. of 2nd transistor = Rs. | ❨ | 100 | x 960 | ❩ | = Rs. 1000 |
96 |
So, total C.P. = Rs. (700 + 1000) = Rs. 1700.
Total S.P. = Rs. (840 + 960) = Rs. 1800.
∴ Gain % = | ❨ | 100 | x 100 | ❩% | = 5 | 15 | % |
1700 | 17 |
⟹ x = | ❨ | 18700 x 115 | ❩ | = 25300. |
85 |
Hence, S.P. = Rs. 25,300.
⟹ C.P. of 12 balls = S.P. of 17 balls = Rs.720.
⟹ C.P. of 1 ball = Rs. | ❨ | 720 | ❩ | = Rs. 60. |
12 |
C.P. of 1 orange = Rs. | ❨ | 350 | ❩ | = Rs. 3.50 |
100 |
S.P. of 1 orange = Rs. | ❨ | 48 | ❩ | = Rs. 4 |
12 |
∴ Gain% = | ❨ | 0.50 | x 100 | ❩% | = | 100 | % = 14 | 2 | % |
3.50 | 7 | 7 |
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
∴ Required percentage = | ❨ | 295 | x 100 | ❩% | = | 1475 | % = 70% (approximately). |
420 | 21 |
C.P. = Rs. | ❨ | 100 | x 392 | ❩ | = Rs. | ❨ | 1000 | x 392 | ❩ | = Rs. 320 |
122.5 | 1225 |
∴ Profit = Rs. (392 - 320) = Rs. 72.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
∴ Gain = | ❨ | 80 | x 100 | ❩% = 5%. |
1600 |
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
∴ | ❨ | 20 - x | x 100 = 25 | ❩ |
x |
⟹ 2000 - 100x = 25x
125x = 2000
⟹ x = 16.
Number of such number =14
∴ Required percentage = | ❨ | 14 | x 100 | ❩% = 20%. |
