A. 56: 99: 69 B. 99: 56: 69 C. 56:99:69 D. 49: 69: 56 Answer Workspace Report Discuss Answer with explanation Answer: Option C Explanation if u assume x and y and solving u will be annoyed. Provided 1/4 is the saving, 3/4 is the expenditure so Expenditure=3, Income = 4 first make A’s Income and Expenditure ratio parts as below A 7*8 9*7 12*7 8*7 9*7 15*7 Now make first one as 4 parts by multiplying 4 and second make 3 parts by multiplying 3 A’s Income = 7*8*4 = 224 A’s Expenditure = 8*7*3=168 Saving = 56 Now B’s Income = 9*8*4 = 288 B’s Expenditure = 9*7*3=189 Saving = 99 A’s Income = 12*8*4 = 384 B’s Expenditure = 15*7*3=315 so Saving = 69 Ratio 56:99:69.
