B. 160 ?
Went by brute force (5+mins), must be some better way to do it...
B=444 - (A+C)
A's saving = 20% = (1/5)A
B's saving = (3/20)B
C's saving = (1/4)C
Using the given ration to get A & C in B form:
[(1/5)A]/[(3/20)B]=7/6 => A=(7/8)B
Similarly C=(9/10)B
So B= 444 - [(7/8)B + (9/10)B]
Solving this equation; B=160

Spendings of A, B and C are 80%, 85% and 75%. so we can derive that total spending to be 80% of the total.
Total salary is 444, which means total spending (80%) is approx. $ 355.2 and savings is $ 88.8. B's share in it is 6/22 or approx. $ 24 which 15% of his earning. Hence B's salary should be $ 160.
Is this right OA?
