We know Zakib spends 30% of his income on education, Supriyo spends 40%. However, without their actual incomes, we cannot compare the absolute amounts spent.
Statement A tells us Zakib spends more on recreation than Supriyo, but this does not help determine incomes or education expenditure directly.
Statement B tells us Supriyo spends more on healthcare than Zakib, but again does not relate to total income.
Even together, the two statements do not provide a link between incomes, so the question cannot be answered.
