E

We can write it as -> 16x = yx

16x = yx + 4
x(16-y) = 4

we know x and y are +ve integers. Hence, y can be 15,14 or 12.

Sum = 41

How do we get from 16x/y = x + 4. To 16x = yx +4?

Re: Quant Question of the Day Chat [#permalink]
We’re putting in the values and checking. Y and X should always be positive integers and for the values of y = 15, 14 or 12 we’re getting +ve value of x. Any lower value will result in -ve value or fractional value of x.

Exactly because after down payment, she is left with 6510. Which divides evenly by 155 and gives 42. If there would have been some interest on the remaining amount - then 48 would have been a possibility. As per above question, 42 should be the right answer
