Question

$A,B$ and $C$ enter into partnership by making investments in the ratio $3:5:7$. After a year, $C$ invests another Rs. $337600$ while $A$ withdraws Rs. $45600$. The ratio of investments then changes to $24:59:167$. How much did $A$ invest initially?

• A. Rs. $45600$
• B. Rs. $96000$
• C. Rs. $141600$
• D. None of these

Answer 1

The correct option is C Rs. $141600$

Let initial investments by $A,B$ and $C$ are $3x,5x,7x$

After a year:

$A$'s investment $=3x-45600$

$C$'s investment $=7x+337600$

$(3x-45600):5x:(7x+337600)=24:59:167$

Solving this we will get $x=47200$

So, A's initial investment was $=3x=3\times 47200=141600$
