If the annual income of a, b and c are in the ratio 1 :3 : 7 and the total annual income of a and c is rs. 8,00,000, then the monthly salary of b (in rs.) is:

Answer 1

Answer:

B = rs 1,00,000

Step-by-step explanation:

let annual income of 'a' be= 1x

annual income of 'b' be= 3x

annual income of 'c' be =7x

therefore:. 1x:3x:7x

given: a+c= rs. 8,00,000

or x+7x=8x

8x= rs. 8,00,000

x= rs 8,00,000÷8

x = 1,00,000

we have x

now, B=3x

= 3 * 1,00,000

= 3,00,000

hence, b = 3,00,000
