1)

Three persons, X, Y and Z started a partnership business investing money in the ratio of $5:4:2$ respectively for a period of $3$ years. What is the amount received by X as his share profit?

I. Total amount invested in the business in Rs. $22,000$.

II. Profit earned at the end of $3$ years is $\frac{3}{8}$ of the total investment.

III. The average amount of profit earned per year is Rs. $2750$.


A) I or II or III

B) Either III only, or I and II together

C) Any two of the three

D) All I, II and III are required

E) None of these

Answer:

Option B

Explanation:

I and II give, profit after $3$ years = Rs. $\left(\frac{3}{8}\times 22000\right)$ = Rs. $8250$.

From III also, profit after $3$ years = Rs. $(2750\times 3)$ = Rs. $8250$.

$\therefore$ X's share = Rs. $\left(8250\times\frac{5}{11}\right)$ = Rs. $3750$.

Thus, (either III is redundant) or (I and II are redundant).

$\therefore$ Correct answer is (B).
