Amar, Bhavan, Chetan and Dinesh have a total of ₹150 with them. Amar has one-fourth of the total amount with the others(except Amar). The amount with Amar (in ₹) is:

37.5 30 25 20

30

Amar + Bhavan + Chetan + Dinesh = Rs. 150 Let Amar have Rs. x out of 150. So, the amount with others = (150 - x) ⇒ 4x = (150 - x) ⇒ 5x = 150, ⇒ x = 30. Therefore, Amar has Rs. 30.
