Pie chart l and Pie chart ll show the break up — according to different expenditure heads and savings of the incomes of Mr. and Mrs. Anand respectively. Pie chart III shows the break up — according to the type of savings — of the total savings of the couple (i.e., the savings of Mr. and Mrs. Anand put together).

Q. |
If the ratio of the income of Mr. Anand to that of Mrs. Anand is 3 : 1, the total savings of the couple invested in PPF as a percentage of Mr. Anand’s savings are: |

✖ A. |
50% |

✖ B. |
65% |

✔ C. |
72% |

✖ D. |
78% |

**Solution:**

Option(**C**) is correct

Given ratio of Incomes is 3 : 1

⇒ Ratio of savings = 5 : 7

Let the total savings be Rs.12

Investments In PPF = 30% of total savings

$⇒ 30\% \text{ of }12 = 3.6$

Required percentage:

$= \dfrac{3.6}{5}×20$

$= \textbf{72%}$
