Discussion :: Partnership
-
A, B and C enter into a partnership in the ratio \(\frac {7 } { 2 } \) : \( \frac { 4 } { 3 }\) : \( \frac { 6 } { 5 }\) After 4 months, A increases his share 50%. If the total profit at the end of one year be Rs. 21,600, then B's share in the profit is:
Answer : Option D
Explanation :
Ratio of initial investments =[\(\frac {7 } { 2 } \)\(: \frac { 4 } { 3 }\):\( \frac { 6 } { 5 }\)]= 105 : 40 : 36
Let the initial investments be 105x, 40x and 36x.
A : B : C =[105x x 4 +\(\frac { 150 } { 100}\)x 105x x 8]: (40x x 12) : (36x x 12)
= 1680x : 480x : 432x = 35 : 10 : 9.
Hence, B's share = Rs.[21600x\( \frac { 1 0} { 54 } \)]= Rs. 4000.
