दिलेले आहे:

A चा वाटा : (B + C) चा वाटा = 5 : 9 

C चा वाटा : (A + B) चा वाटा = 3 : 7 

A + B + C = 7560

गणना:

A : (B + C) = 5 : 9 आणि C : (A + B) = 3 : 7

A + B + C = 7560

समजा, A चा वाटा = 5x आणि (B + C) यांचा वाटा = 9x आहे.

⇒ 5x + 9x = 7560

⇒ x = 7560/14 = 540

अशाप्रकारे, A चा वाटा = 5 × 540 = 2700 

आणि (B + C) = 9 × 540 = 4860 -----(1)

त्याचप्रमाणे, समजा, C चा वाटा = 3x आणि (A + B) यांचा वाटा = 7x आहे.

⇒ 3x + 7x = 7560

⇒ x = 7560/10 = 756

अशाप्रकारे, C चा वाटा = 3 × 756 = 2268 

C चे मूल्य समीकरण (1) मध्ये ठेवल्यास 

⇒ B + 2268 = 4860

⇒ B = 4860 - 2268 = 2592

म्हणून, B चा वाटा 2592 रुपये आहे.
