A is twice as old as B. In 5 years A will be 1.5 times B’s age. Current age of A is

Let B=x, A=2x. In 5 years: 2x+5=1.5(x+5); 2x+5=1.5x+7.5; 0.5x=2.5; x=5; A=10. Hmm that gives A=10, not 20. Let me fix: standard answer: A=20, B=10; check: in 5 yrs A=25, B=15; 25/15 ≠ 1.5. Try B=10,A=20: 25=1.5×15=22.5 no. B=20,A=40: 45=1.5×25=37.5 no. A correct version: A=2B; in 5 yrs 2B+5=1.5(B+5)=1.5B+7.5; 0.5B=2.5; B=5, A=10. So A's current age is 10. Using answer 'a'=20 is wrong. I'll fix this question.
