Amar bought three kgs of tomato at ₹20/kg. Akbar bought two and a half kgs of banana at ₹30/kg. Anthony bought a three-quarters kg of ginger at ₹60/kg. Who spent the most money ? [ 3 marks ]

Solution:
Let's figure out the amount spent by each person.

Amar bought three kgs of tomato at ₹20/kg
money spent = $3\times ₹20=₹60$ [ 1 mark ]

Akbar bought two and a half kgs of banana at ₹30/kg
money spent = $2\frac{1}{2}\times ₹30=2\times ₹30+\frac{1}{2}\times ₹30=₹60+₹15=₹75$ [ 1.5 marks ]

Anthony bought a three-quarters kg of ginger at ₹60/kg
money spent = $\frac{3}{4}\times ₹60=₹45$
[ 0.5 mark ]

Hence, Akbar spent the most money.
