Correct Answer - Option 4 : 4000
GIVEN:
Initial investment of Anil = 5x
Initial investment of Ruhi = 8x
Profit received by Sujeet = Rs.18,000
FORMULA USED:
Profit = Investment x Time
CALCULATION:
Anil : Ruhi : Sujeet
= [(5x x 4) + (10x x 8)] : [(8x x 4) + (4.8x x 8)] : (18x x 8)
= 25x : 17.6x : 36x
⇒ 36x = Rs.18,000
⇒ x = Rs.500
∴ Initial investment of Ruhi = 8 x 500 = Rs. 4000
