Question

The ratio of monthly incomes
of Pawan and Sunil is 4 : 3
and the ratio of their monthly
expenditures is 3:2. If Pawan
and Sunil save Rs. 4000 and
Rs. 6000 respectively per
month, then what is the sum
of their monthly incomes ?​

Answer 1

Answer:

70k

Step-by-step explanation:

Let the monthly income of Pawan & Sunil be 4x & 3x respectively

Let the monthly expenditure of Pawan & Sunil be 3y & 2y respectively

According to the question,

⇒ 4x – 3y = 4000 ...i)

⇒ 3x – 2y = 6000 ...ii)

⇒ (i) × 2 – (ii) × 3

⇒ 8x – 6y – (9x – 6y) = 8000 – 18000

⇒ -x = -10000

⇒ x = 10000

Sum of their monthly income = 4x + 3x = 7x

= Rs. 70000
