Question:

A, B and C enter into partnership. A advances Rs. 1200 for 4 months, B Rs.1400 for 8 months, and C Rs.1000 for 10 months. They gain 585 altogether. Find the share of each.

Options:

B)

Rs. 108, Rs. 252, Rs. 225

C)

Rs. 128, Rs. 242, Rs. 215

D)

Rs. 138, Rs. 262, Rs. 245

E)

None of these 

Solution:

Ans: (b) 1200 × 4: 1400 × 8: 1000 × 10

12 : 28 : 25

Sum of the terms of ratios = 65

A’s share =\(\cfrac{12}{65}\times585\) = Rs. 108

B’s share =\(\cfrac{28}{65}\times585\)= Rs.252

C’s share =\(\cfrac{25}{65}\times585\)= Rs. 225
