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
