Q.2. The monthly income of Albert and Bertha are in the ratio 10:9 and their
expenditures are in the ratio 6:7. If albert saves Rs.20,000 per month and Berth
saves Rs. 10,000 per month then find their monthly incomes.​

Answer 1

Step-by-step explanation:

let the monthly income of Albert=Rs10×

and monthly income of Berth=Rs9×

10×-20,000/9×-10,000=6/7

(10×-20,000)7=(9×-10,000)6

70×-140000=54×-60000

70×-54×=140000'60000

16×=80000

×=80000/16

×=5000

Albert monthly income=Rs50000

Berth monthly income=Rs45000
