Question

Abel y Laura juegan tirando al aire una moneda. Cada vez que sale cara, Abel gana cuatro puntos y Laura pierde dos. Y si sale cruz, al revés. Después de 12 tiradas, Laura lleva seis puntos negativos. ¿Cuántos lleva Abel?

Answer 1

Given that the points are awarded such that for every win Abel gets, he gets 4 points and Laura loses 2 points, then after 12 hours the number of points that Abel will have won will be:
Total points=[number of times Laura lost]x4
number of times Laura lost=[number of Laura's points]/2=-6/2=-3
thus the total points for Abel will be:
3x4=12 points
the answer is 12 points
