दिया गया है:

आय अनुपात (A : B) = 7 : 10

व्यय अनुपात (A : B) = 2 : 3

A की बचत = ₹1,000

B की बचत = ₹1,000

प्रयुक्त सूत्र:

आय = व्यय + बचत

माना, A की आय = 7x, B की आय = 10x

माना, A का व्यय = 2y, B का व्यय = 3y

गणना:

7x - 2y = 1000 …(1)

10x - 3y = 1000 …(2)

(1) को 3 से गुणा करें: ⇒ 21x - 6y = 3000

(2) को 2 से गुणा करें: ⇒ 20x - 6y = 2000

घटाएँ: ⇒ (21x - 6y) - (20x - 6y) = 3000 - 2000

⇒ x = 1000

⇒ B की आय = 10x = 10 × 1000 = ₹10,000

सही उत्तर ₹10,000 है।
