Arun, Kamal and Vinay invested Tk. 8000, Tk. 4000 and Tk. 8000 respectively in a business. Arun left after six months. If after eight months, there was a gain of Tk. 4005, then what will be the share of Kamal?

A Tk. 890

B Tk. 1335

C Tk. 1602

D Tk. 1780

Solution

Correct Answer: Option A

Arun : Kamal : Vinay = (8,000 x 6) : (4,000 x 8) : (8,000 x 8)

= 48 : 32 : 64

= 3 : 2 : 4.

So, Kamal's share = Tk. (4005 x 2/9)

= Tk. 890.
