A.Rs. 23600
B.Rs. 22500
C.Rs. 24000
D.Rs. 25200
E. None of these
Sol:
The share of P, Q and R,
= > [12000 * 5 + 15000 * 7] : [15000 * 12] :
[18000 * 8 + 15000 * 4]
= > [60000 + 105000] : [180000] : [144000 +
60000]
= >165000 : 180000 : 204000
= >55 : 60 : 68
183’s = 73200
1’s = 400
The share of Q = 60’s = Rs. 24000
