Correct Answer - Option 2 : Rs. 20
Given:
Total amount = Rs. 120
A's share = Rs. 20 + B's share = C's share - 20
Calculations:
Let the share of A be Rs. y.
B's share = y - 20
C's share = y + 20
As given, Total amount = Rs. 120
⇒ y + y - 20 + y + 20 = 120
⇒ 3y = 120
⇒ y = 40
B's share = y - 20
⇒ 40 - 20
⇒ 20
∴ B's share is Rs. 20.
