Then, | 1920 - x | x 100 = | x - 1280 | x 100 |
x | x |
⟹ 1920 - x = x - 1280
⟹ 2x = 3200
⟹ x = 1600
∴ Required S.P. = 125% of Rs. 1600 = Rs. | ❨ | 125 | x 1600 | ❩ | = Rs 2000. |

∴ Required ratio = |

∴ Gain in 1 year = Rs. | ❨ | 225 | ❩ | = Rs. 112.50 |

Since the principal is not given, so data is inadequate.
Note:
Here, original rate is for 1 year(s); the new rate is for only 4 months i.e. ⅓ year(s).
∴ | ❨ | 725 x R x 1 | ❩ | + | ❨ | 362.50 x 2R x 1 | ❩ | = 33.50 |
100 | 100 x 3 |
⟹ (2175 + 725) R = 33.50 x 100 x 3
⟹ (2175 + 725) R = 10050
⟹ (2900)R = 10050
⟹ R = | 10050 | = 3.46 |
2900 |
∴ Original rate = 3.46%
Principal = Rs. | ❨ | 100 x 5400 | ❩ | = Rs. 15000. |

Then, 3(y - x) = (2y - x) ⟹ y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
∴ Profit % = | ❨ | x | x 100 | ❩% = 100% |

Cost Price of 1 toy = Rs. | ❨ | 375 | ❩ | = Rs. 31.25 |
12 |
Selling Price of 1 toy = Rs. 33
So, Gain = Rs. (33 - 31.25) = Rs. 1.75
∴ Profit % = | ❨ | 1.75 | x 100 | ❩% | = | 28 | % = 5.6% |
31.25 | 5 |
C.P. of 30 articles = Rs. | ❨ | 5 | x 30 | ❩ | = Rs. 25. |

S.P. of 30 articles = Rs. | ❨ | 6 | x 30 | ❩ | = Rs. 36. |
5 |
∴ Gain % = | ❨ | 11 | x 100 | ❩% = 44%. |
25 |
Selling Price (S.P.) = Rs. 5800.
Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.
Gain % = | ❨ | 300 | x 100 | ❩% | = 5 | 5 | % |

C.P. of 1 orange = Rs. | ❨ | 350 | ❩ | = Rs. 3.50 |

S.P. of 1 orange = Rs. | ❨ | 48 | ❩ | = Rs. 4 |

∴ Gain% = | ❨ | 0.50 | x 100 | ❩% | = | 100 | % = 14 | 2 | % |
