Answer 1

Answer:

Rs. 30,600

Step-by-step explanation:

Let Anita's monthly income be = Rs. x

•°• Bina's monthly income = 90% of Anita's monthly income

= 90/100 × x

= 9x/10

Given,

Mr. Sen's annual income = Rs. 7,75,200

•°• Mr. Sen's monthly income = 7,75,200÷12

(1 year = 12 months)

= Rs. 64,600

Acc. to the question :

Bina's monthly income + Anita's monthly income =

Mr. Sen's monthly income

9x/10 + x = 64,600

Taking LCM

19x/10 = 64,600

x = 64,600 × 10 ÷ 19

= 34,000

Anita's monthly income = x = Rs. 34,000

•°• Bina's monthly income = 90% of Anita's monthly income

= Rs. 30,600
