The given pie diagram shows how a student spent his pocket money amounting to ₹3,500 during the course of a month.

How much more money (in ₹) did he spend on food as compared with what he spent on entertainment?  

Total pocket money: ₹3,500

Percentage of amount spent on food = 50%

Percentage of amount spent on entertainment = 20% 

​$$\text{Amount spent in a category} = \left(\frac{\text{Percentage}}{100}\right) \times \text{Total money}$$   

Solution:   ​

As we know, the expenditure percentage on food is higher than entertainment.

difference between percentage of food and entertainment = 50 - 20 = 30%   

Now,  $$\frac{30}{100}\times 3500 = ₹1050$$   

Thus, Student spent ₹1050 more on the food as compared to entertainment.
