B) 435 crore
C) 348 crore
D) 345 crore

Answer

Option (A)

Solution

As per CAT 2017 – Quantitative Aptitude – Arithmetic – Ratios, we can see that
Profit of C1 = 9x
Profit of C2 = 10x = 18y — (1)
Profit of C3 = 8x
Profit of C4 = 19y
Profit of C1 = 20y
Taking eq(1), we get x = 9y/5
20y = 19 + 9x
Putting value of x and y in the above eq we get, x=9 and y=5
So, Total profit = 9x +10x + 8x + 19y + 20y = 438 crore
