Question

If the expenditure on food is Rs 3000,what is the expenditure on education of children?

Answer 1

Expenditure on food =Rs.3000

Expenditure on food shown in diagram =120o

Expenditure on education shown in diagram =60o

As we see that, Expenditure on education is half of expenditure on food (120degree/2  =60  degree )

∴   Expenditure on education =  1/2  ×Rs.3000   =Rs.1500
