If 110% of A's income = 120% of B's income = 130% of C's income and sum of their incomes is Rs. 4310, then B's income is?

1430

110% of A = 120% of B = 130% of C

110 of A = 120 of B = 130 of C

 11 A = 12 B = 13 C

Now,

       A          :          B           :            C

⇒ 12 × 13   :     11 × 13     :        11 × 12

⇒   156       :        143         :           132        =    431 (total)

⇒ 431 R = 4310

⇒ 1R = 10

⇒ B = 143 R = 1430
