Answer 1

answer: 2601

steps:We think that Mona invested 10% less than Raghu and Sonu invest 10 % more than Mona so, Raghu and Sonu's investment is same so, there we let think total = 100% so the percentage of Sonu and Raghu together is 90 Percentage so the one person is 45 percentage

Mona percentage=10%

Mona ten percent will come into money so

5780×10/100

= rs.578 Mona invest

Now, if first we find investment of Sonu because if there investment are same so, Raghu also invest same

5780*45/100

2601 so, Sonu and Raghu invested 2601

to check my formula

2601+ 2601 + 578= 5780
