D

After increment price of X and Y together = Rs 175.5Price before increment = | 175.5 | × 100 = Rs 150 |

117 |

Price of apple X = | 150 | × 2 = Rs 60 |

5 |

Price of apple Y = | 150 | × 3 = Rs 90 |

5 |

X's price increased by 20%, X's price = 60 × 120% = Rs 72

Y's new price = Rs.(175.5 – 72) = Rs.103.5

Y's price increased by | 103.5 – 90 | × 100 = 15% |

90 |

Hence, option D is correct.
