Rs. 2420 were divided among A, B and C so that A : B = 5

Rs. 2420 were divided among A, B and C so that A : B = 5 : 4 and B : C = 9 : 10 then C gets

A : B = 5 : 4 = 45 : 36
B : C = 9 : 10 = 36 : 40
∴ A : B : C = 45 : 36 : 40
Sum of the terms of ratio
= 45 + 36 + 40 = 121

∴ C’s share = Rs.		40	× 2420
		121

= Rs. 800
