The annual income of D is how much (in rupees) less than that of A?
A4600
B52200
C55200 ✓ Correct
D4900
Correct answer: (C) 55200
Explanation
D's annual income is 55200 less than A's, so the answer is 55200.
A's monthly income is 105800 and D's is 101200.
So each month D earns 4600 less than A.
Over a year this gap is 4600 times 12.
That equals 55200.
So D's annual income is 55200 below A's.
So the answer is 55200.
