Suppose, C1, C2, C3, C4, and C5 are five companies. The profits made by C1, C2, and C3 are in the ratio 9 : 10 : 8 while the profits made by C2, C4, and C5 are in the ratio 18 : 19 : 20. If C5 has made a profit of Rs 19 crore more than C1, then the total profit (in Rs) made by all five companies is:
Explanation:
C5 – C1 = 19. ∴ 100x - 81x = 19 ⇒ x = 1
∴ Total profit = 81x + 90x + 72x + 95x + 100x = 438x = 438 crore.
Hence, option (a).
