There are three business partners A, B and C such that capital investment of A is ₹20,000 more than twice the investment of B and C invests ₹60,000 less than A. If they joining invest ₹4,80,000, their capital ratio is :

11 : 5 : 8

The correct answer is Option (3) → 11 : 5 : 8

Investment of B = Rs. $x$

Investment of A = Rs. $(2x + 20,000)$

Investment of C = Rs. $(2x - 40,000)$

$A+B+C=4,80,000$

$⇒5x-20,000=4,80,000$

$⇒x=1,00,000$

$⇒A:B:C=2,00,000:1,00,000:1,60,000$

$=11:5:8$
