Mr. Deepak is Paid commission of 5% on cash sales and 4% on credit sales. If on a total sales of Rs.50000 he is paid Rs. 2400 find the amount of cash and credit sales.

Let cash sale be x.
So, 5% of total sale = 5% of x =50,000.
X= 5x/100+4/100+(50,000-x)
2400=5x/100+4/100+(50,000)
2400=5x/100+2,00,000-4x/100
By shifting 100 to another side
2400×100=5x+2,00,000-4x
240000=5x+2,00,000-4x
240000=5x-4x+2,00,000
240000=x + 2,00,000
240000-2,00,000=x
40,000=x
Therefore,total cash sale is 40,000.
And credit sale is 50,000-40,000=10,000
