Question

A started a project by investing rs. X and after 6 months, b invested rs. 4,000 more than the what a had invested. At the end of the year the ratio of the overall profit to that of b was 7 : 3. What was the value x?

Answer 1

Answer:

Ratio of the equivalent capitals of A, B and C for 1 month

= (20000 x 6 + 12000 x 6) :

(28000 x 6 + 20000 x 6) :

(36000 x 6 + 44000 x 6)

= (120 + 72) : (168 + 120) :

(216 + 264)

= 192 : 288 : 480

= 2 : 3 : 5

If the total profit at the end of the year be Rs.x, then

C's share = 5/10 x x = Rs.x/2

x/2 = 12550

x = 2 x 12550

= Rs. 25100
