(2) Let salaries of A, B and C are x, y and (1450 - x - y ), respectively. Then, 40% of x : 35% of y : 30% of (1450 - x - y ) = 14: 21:15 Taking first two terms of above ratio, we get
40x
35y
=
14
21
⇒ x =
7
12
y Now, taking last two ratio, we get
35y
30(1450−x−y)
=
21
25
⇒
7y
6(1450−x−y)
=
21
25
⇒ 5y = 8700 - 6x - 6y ⇒ 11 y + 6 x
7
12
y = 8700 ⇒
29
2
y = 8700 2 ⇒ y = ₹ 600 Hence, salary of B is ₹ 600
