Solution:

Let the amount invested by Company A in 2009 = x
Let the amount invested by Company B in 2009 =

x/2

Total amount invested by both the companies = 27 lakh
So,

x+x/2= 27,00,000

⇒3/2x= 27,00,000

⇒x = 2/3× 27,00,000

= 18 Lakh
Amount invested by Company A = 18 Lakh
Amount invested by Company B = 9 lakh
Profit of Company A = 75%
Profit of Company B = 80%

∴18,00,000×75/100

+9,00,000×80/100

= 13,50,000 + 7,20,000 = Rs 20,70,000
