Bani and Rani together started a bus ness by investing ₹12 lakh and ₹15 lak respectively, later Ashish joined them wit some investment. All of them invested the capital for 5,6 , and 8 years, respectivel Find the Ashish's investment if they earne total profit of $₹ 28,38,200$ and the Rani share is $₹ 11,10,600$.

Percentages, Profit and Loss, Discount and Partnership

Solution:

Let Ashish's investment $=₹ x$
Ratio of profit share $=12$ lakh $\times 5: 6$ lakh $\times 15: 8 \times x$
$=6000000: 9000000: 8 x$
$=750000: 1125000: x$
Rani's profit share $=$
$\frac{1125000}{750000+1125000+x} \times 2838200=1110600 $
$=\frac{1125000 \times 2838200}{1875000+x}=1110600 $
$=\frac{11250 \times 2838200}{1875000+x}=11106 $
$=2875000=1875000+x $
$\Rightarrow x=₹ 1000000$
Thus, investment of Ashish $=₹ 1000000$.
