If 120% of A's income = 140% of B's income = 160% of C's income and sum of their incomes is Rs. 1460, then B's income is?

480

120% of A = 140% of B = 160% of C

120 of A = 140 of B = 160 of C

 6 A = 7 B = 8 C

Now,

       A          :          B           :            C

⇒ 8 × 7       :     6 × 8          :         6  × 7

⇒   56          :        48           :           42        =    146 (total)

⇒ 146 R = 1460 

⇒ 1R = 10

⇒ B = 48 R = 480
