Profitability and liquidity ratios

A ratio only means something against a benchmark: last year, a competitor, or the industry. Paper 2 rewards the comparison, not the arithmetic. Memorise the formula; the exam gives no hint.

GPM = (Sales − COGS) ÷ Sales × 100 = (480,000 − 278,400) ÷ 480,000 = 42.0%

A firm is profitable but cannot pay suppliers. Most likely cause?

ALow gross profit margin
BLong debtor days
CHigh depreciation charge
Correct. Profit and cash differ in timing: customers paying late (long debtor days) drains cash while profit on paper stays intact.

I teach IB Business Management in Mexico City, SL and HL. I built this site because what I wanted to hand my students did not exist in one place: short lessons on the current guide, questions that explain why the wrong answer was tempting, and practice papers that look like the real thing without being past papers. Everything here is what I use with my own groups. If you find a mistake or something is missing, write to me and I will fix it.

Doy clases de IB Business Management en la Ciudad de México, SL y HL. Hice este sitio porque lo que quería darles a mis alumnos no existía en un solo lugar: lecciones cortas sobre la guía vigente, preguntas que explican por qué la respuesta equivocada era tentadora y practice papers que parecen los de verdad sin ser papers pasados. Todo lo que hay aquí es lo que uso con mis propios grupos. Si encuentras un error o falta algo, escríbeme y lo corrijo.

How it works

Short lessons, then a quiz that explains the wrong answers.

Lecciones cortas y un quiz que explica las respuestas incorrectas.

A lesson takes eight to twelve minutes and ends in a quiz. When you miss a question you see why the distractor was tempting. The toolkit tools come with a case to apply them on, because Paper 2 will not ask you to define SWOT; it will ask you to use it.

Una lección toma de ocho a doce minutos y termina en un quiz. Cuando fallas una pregunta ves por qué el distractor era tentador. Las herramientas del toolkit vienen con un caso para aplicarlas, porque el Paper 2 no te pedirá definir el SWOT: te pedirá usarlo.

Lessons

Eight to twelve minutes each, with the company named and the exam trap marked.

De ocho a doce minutos cada una, con la empresa con nombre y la trampa del examen señalada.

Unit 2.4

Motivation and demotivation

Herzberg separated hygiene factors from motivators. Fixing pay stops dissatisfaction; it does not create motivation. The exam trap: treating salary as a motivator.

More fixed cost to cover with the same contribution per unit means more units are needed. BEQ = FC ÷ (P − VC).
