Let the amount invested by Anil Bobby and Chintu be x, y, and z.
Considering
x+y+z=100×p. Given Anil's share was 70 percent =
70×p As per the information provided :
His share of profit decreases by
₹420 if the overall profit goes down from
18% to
15% Since the profits are distributed in the ratio of their investments:
With a
3% decrease in the profits the value of profit earned by
A decreased by
Rs‌420 which was
70% of the total invested.
Hence for all three of them would be combined losing
(420).()=600 Hence 3 % profit was equivalent to
Rs‌600 The initial investment is equivalent to
Rs‌20000 This is the total amount invested.
Chintu's profit share increased by Rs 80 when the profit percentage increased by 2 %. A 2 percent increase in profit is equivalent to
Rs‌20000×=Rs‌400 Of which
Rs‌80 is earned by Chintu which is
20% of the total
Rs‌400 Hence he invested
20% of the total amount.
Bobby invested the other
10%.
10% of
Rs‌20000=Rs‌2000
