The monthly incomes of two friends Ashish and Kiran,

Let the monthly incomes of Ashish and Kiran be $5x$ and $8x$ respectively. Their monthly expenditures are $E_A = 5x - 75,000$ and $E_K = 8x - 75,000$.

Given that the ratio of their expenditures is $1:2$, we have:

$ \frac{5x - 75,000}{8x - 75,000} = \frac{1}{2} $

Solving this:

$2(5x - 75,000) = 8x - 75,000$

$10x - 150,000 = 8x - 75,000$

$2x = 75,000$

$x = 37,500$

So, Ashish's monthly income = $5x = 5 \times 37,500 = 1,87,500$

✅ Correct Answer: ₹1,87,500
