Three boys shared some oranges. The first received 13 of the oranges, the second received 23 of the remainder. If the third boy received the remaining 12 oranges, how many oranges did they share?

A.

60

B.

54

C.

48

D.

42

Correct answer is B

let x represent the total number of oranges shared, let the three boys be A, B and C respectively. A received 13 of x, Remainder = 23 of x . B received 23 of remainder (i.e.) 23 of x

∴ C received 23 of remainder (23 of x) = 12

13 x 2x3 = 12

2x = 108

x = 54
