A, B, and C started a business by investing a sum of money in which A invested 25% of the total, B invested 30% of the remaining and C invested the remaining. Find the ratio of profit at the end of the year.
Answer & explanation
Correct answer: option 3
25% = \(\frac{1}{4}\)
30% =\(\frac{3}{10}\)
Let total investment is = 40 (LCM of the denominators 4 and 10)
ATQ,
Investment:
A = 40× 25% = 10
Remaining = 40 - 10 = 30
B = 30 × 30% = 9
Remaining = 30 - 9 = 21
C = 21
*Profit ratio = Investment ratio (if time of investment is same for all)
Therefore,
Profit Ratio = 10 : 9 : 21
