Answer 1

amritha invest rs 7200

Answer 2

Answer:

Investment made by Amrita = Rs. 7152

Step-by-step explanation:

Let Vaishali has invested Rs. 100

Amrita invested 10% less than Vaishali.

⇒ Amrita invested = 90% of 100

                               = Rs. 90

Sheila invested 20% more than Amrita

⇒ Sheila invested = 110% of 100

                               = Rs. 110

Now, Total percentage of investment = 100 + 90 + 110

                                                               = 300

Total sum of investment = Rs. 23840

So, One percentage part = 23840/300

                                          = 79.47

Hence, Amrita investment = 90 × 79.466

                                              = Rs. 7152
