let us consider following picture and question:

INCOME: 1. Money from fund raising programmes, 2. Grant from the government, 3. Contributions from individuals, 4. Contributions from corporations, 5. Contributions as commodities. EXPENDITURE: 1. Education of the illiterate, 2. Food for the poor, 3.Management and salary of staff, Expenses to organise fund-raising programmes. Above charsts show the amounts of an NGO Income for the year $1998-1999 = 55 Mn.$ Expenditure for the same year = $54Mn$.
question :
If the government stops the grant and the expenditure pattern remains the same, then what will be the decrease in the money spent for the education of illiterate?
now what i have done is that if income is $55$,then for grant,proportion from this income to grant is $55*(50/360)=7.64$,if we will stop granting, he will have left $55-7.64=47.36$,for Education of the illiterate is $54*(150/360)=22.5$,what else i should do?
Your 7.64 will now not be distributed among projects, so Education for the illiterate will lose $7.64*\frac{150}{360}$
