The ratio of weekly pocket money earned by Tom, Zipho and Katlego is 2 : 3 : 4. If Tom earns R50 per week, how much do Zipho and Katlego earn?
R100
R200
R75
Zipho earns R75 and Katlego earns R100.
Explanation:
Tom earns R50, according to the ratio of 2:3:4, Zipho earns 3 parts (2 parts more than Tom) and Katlego earns 4 parts (3 parts more than Tom).
Therefore, Zipho earns 3/2 * R50 = R75 and Katlego earns 4/2 * R50 = R100.
