Question

Kashish and Sheena started a business by investing Rs 2600 and Rs 2400 respectively. After 7 months, they added Rs 600 and Rs 800 respectively. 33% of the total profit earned after a year is given in donation. If after giving donation, the difference between the shares of Kashish and Sheena is Rs 350, find the total profit earned after a year.

Answer 1

Ratio of shares of profit of Kashish : Sheena is,

$\Rightarrow 2600\times 7+3200\times 5:2400\times 7+3200\times 5$

$\Rightarrow 171:164$

Let Total profit be $y$ Rs.

Let profit left after giving donation be $x$ Rs.

So the difference between their profits is,

$\Rightarrow \frac{171-164}{171+164}\times x=350$

$\Rightarrow \frac{7}{335}\times x=350$

$\Rightarrow x=16750$ Rs

Now,

$33\%$ of profit is given as donation

$(100-33)\%$ of $y=16750$,

$\Rightarrow \frac{77}{100}\times y=16750$

$\Rightarrow y=25000$ Rs

Thus total profit $=25000$ Rs.
