Answer 1

This is the answer for your question

Answer 2

Raghu invested Rs 6000.

Explanation:

Let x be the money( in rupees) invested by Raghu.

Then, the money invested by Mohit = x-0.1 x= (1-0.1)x   = 0.9x

The money  invested by Pradeep =0.9x+0.2(0.9x)=0.9x+0.18x=1.08x

According to the question ,we have

Investment by Raghu + Investment by Mohit +  Investment by Pradeep =  Rs 17880

$x+0.9x+1.08x=17880$

$2.98x=17880\\\\\Rightarrow\ x=\dfrac{17880}{2.98}=6000$

Hence, Raghu invested Rs 6000.
