Question
The average expenditure of Mr. Sharma for January to
June is Rs. 4200 and he spent Rs. 1200 in January and Rs. 1500 in July. The average expenditure for the months of February to July is?Solution
ATQ, Total expenditure of Mr. Sharma for January to June = 6 × 4200 = Rs 25200 Total expenditure of Mr. Sharma for the month February to June = 25200 – 1200 = Rs 24000 Total expenditure of Mr. Sharma for the months February to July = 24000 + 1500 = Rs 25500 ∴ Average expenditure for the months February to July = 25500/6 = Rs 4250
