Q. |
The percentage increase in the savings from2001 to 2002 is how many percentage points more than that of transport? |

✖ A. |
66.66 |

✔ B. |
100.00 |

✖ C. |
133.33 |

✖ D. |
150.25 |

✖ E. |
200.75 |

**Solution:**

Option(**B**) is correct

**Savings in 2001:**

$=\dfrac{1,20,000×20}{100} =24,000$

**Savings in 2002:**

$=\dfrac{2,40,000×108}{360}= 72,000$

⇒ % Increase in Savings:

$= \dfrac{48,000}{24,000}×100$

$= 200\%$

**Amount spent on transport in 2001:**

$= \dfrac{1,20,000×5}{100}$

$= 6,000$

**Amount spent on transport in 2002:**

$= \dfrac{2,40,000×36}{360}$

$= 24,000$

⇒ % Increase in the amount spent on transport:

$= \dfrac{18,000}{6,000}×100$

$= 300\%$

The percentage point difference:

$= 200 - 300$

$= -100$

⇒ Less by **100** **percentage points.**

**Alternate method:**

Total salary in 2002 was increased by 100%

Share of saving in 2002 is 30%, when the total salary increased by 100%, share of saving will also be doubled i.e., 60% similarly, the share of transport in 2002 is 20%.

Percentage increase in saving is 20% to 60% i.e., 200%

Percentage increase in transport is 10% to 20% i.e., 100%

Difference in percentage is **100% points**.
