A certain sum is divided between four people A, B, C and D in the ratio 3 : 4 : 7 : 8, respectively. If the amount received by D is ₹408 more than the amount received by B, what is the total amount received by C and D?

₹1,530

A : B : C : D

3 : 4 : 7 : 8

⇒ (D - B) = (8 - 4)units = Rs.408

⇒ 4 units = 408

⇒ 1 unit = Rs. 102.

⇒ (C + D) = (7 + 8) x 102 = 15 x 102 = Rs. 1530.
