Dinesh total percent of his salary is equal to money spend on himself + Dinesh spends money on his social work is equal to 85% + 10% is equal to 95%
then the money left with him is equal to 1250

then 100% - 95% is equal to 5% then 5% of his salary is equal to rupees 1250

5% is equal to rupees 1250
100% is equal to X
at the cross multiplication

so x is =100×1250÷5
125000÷5
25000
