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?
Answer & explanation
Correct answer: option 2
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
