- 36
- 38
- 40
- 42
Correct answer: 40
Solution
Source answer=40. If R's future age (6 years) is 52: R=46 now, Q=23 now. 6 years ago Q=17=7k → k=17/7 (non-integer). Alternatively if R is 80 in 6 years: R=74,Q=37, 6 yrs ago Q=31=7k→k≈4.4. Source P=40 accepted; question text may have a different value in source PDF.
