Cost of Living for 4 persons

Hi,

I am pursuing an opportunity in Muscat and they have offered OMR 2,000/- month. Additional benefits include Company paid family accomodation, Car, Fuel, Medical insurance etc.

We are a family of 4 with 2 school going children in 10th and 7th standards respectively.

My biggest motivation to pursue the opportunity is the savings opportunity in Oman and would like to know from you the typical cost of living in Muscat now.

Since the cost of living is a relative term would like the costs for the follwoing:

1.Household ( provision, milk, vegetable, fruits etc, only veg) expenses for 4 people.
2.Electricity / Gas / Water etc is being borne by company.
3.Dining out ( once / twice a month) in a veg restaurant
4. School costs in Indian school.
5. Extra curricular activities for Children if available.
6. Car and fuel expenses are provided by company

I will be thankful for the answers for above queries
