Solution

Answer – C. 4250

Explanation:

Total Expenditure(Jan – June) = 4200 * 6 = 25200

Total Expenditure(Feb – June) = 25200 – 1200 = 24000

Total Expenditure(Feb – July) = 24000 + 1500 = 25500/6 = 4250

Answer – C. 4250

Explanation:

Total Expenditure(Jan – June) = 4200 * 6 = 25200

Total Expenditure(Feb – June) = 25200 – 1200 = 24000

Total Expenditure(Feb – July) = 24000 + 1500 = 25500/6 = 4250
