1. 255
2. 240
3. 270
4. 225

Answer 1

Correct Answer - Option 4 : 225

Given:

The first amount donated = 15% of monthly income

The second amount donated = 20% more than the first amount.

Formula used:

Final amount = First amount × (100 + percentage value)/100

Calculation:

Let x be the monthly salary of Rakhi

Now first donated amount = 15% of x

⇒ 0.15x

Now the second amount donated = 0.15x × (100 + 20)/100

⇒ 0.15x × 1.2

⇒ 0.18x

According to question:

The second amount donated = 2700

0.18x = 2700

x = 15000

Now first donated amount = 0.15x

⇒ 0.15 × 15000

⇒ 2250

Now 10% of the earlie amount donated =

10% of 2250

⇒ 225

Hence, the correct answer is "225".
