Question

The ratio between the credit and debit of Madhavan is 9:8. If the debit is Rs. 3480 What is the credit ?​

Answer 1

Step-by-step explanation:

x= Monthly income of A

y= Monthly income of B

a = Expenditure of A

b = Expenditure of B

8x=9y

7a = 8b

x-a=500

y-b=500

(8/9)x - (7/8)a = 500

64x-63a=36000

64x-64a=32000

a=4000

b=3500

x=4500

y=4000

Monthly Income of A is 4500
