Question
Sonu invested 10% more than Mona. Mona invested 10% less than Raghu. If the total sum of their investments is Rs 5,780, how much amount did Raghu invest?
Let money invested by Raghu = Rs X say
Money invested by Mona = (9/10)X = 0.9X
Money invested by sonu = (0.9X) ×(110/100) = 0.99x
Also, X + 0.9X + 0.99X = 5780
=> X = 5780/2.89 = 2000
