T.D. = | ❨ | B.G. x 100 | ❩ | = Rs. | ❨ | 270 x 100 | ❩ | = Rs. 750. |
R x T | 12 x 3 |
∴ B.D. = Rs.(750 + 270) = Rs. 1020.
B.G. = | (T.D.)2 | = Rs. | ❨ | 36 x 36 | ❩ | = Rs. 1.62 |
P.W. | 800 |
∴ B.D. = (T.D. + B.G.) = Rs. (36 + 1.62) = Rs. 37.62
T.D. = | B.G. x 100 | = Rs. | ❨ | 6 x 100 | ❩ | = Rs. 50. |
R x T | 12 x 1 |
T.D. = | ❨ | B.G. x 100 | ❩ | = Rs. | ❨ | 24 x 100 | ❩ | = Rs. 120. |
Rate x Time | 10 x 2 |
∴ P.W. = | 100 x T.D. | = Rs. | ❨ | 100 x 120 | ❩ | = Rs. 600. |
Rate x Time | 10 x 2 |
B.G. = | (T.D.)2 | = Rs. | ❨ | 160 x 160 | ❩ | = Rs. 16. |
P.W. | 1600 |

Then, B.G. = Re. | 3 | . |

∴ T.D. = (B.D. - B.G.) = Re. | ❨ | 1 - | 3 | ❩ | = Re. | 22 | . |

Sum = | ❨ | 1 x (22/25) | ❩ | = Rs. | 22 | . |

S.I. on Rs. | 22 | for 1 | 1 | years is Re. 1. |

∴ Rate = | ❨ | 100 x 1 | ❩% |

∴ S.I. on Rs. 450 = Rs. 90.
S.I. on Rs. 540 = Rs. | ❨ | 90 | x 540 | ❩ | = Rs. 108. |
450 |
∴ B.D. = Rs. 108.
Sum = | B.D. x T.D. | = Rs. | ❨ | 72 x 60 | ❩ | = Rs. | ❨ | 72 x 60 | ❩ | = Rs. 360. |
B.D. - T.D. | 72 - 60 | 12 |
So, the number 47 is wrong and must be replaced by 46.
