- ₹110
- ₹120
- ₹130
- ₹100
- ₹110
- ₹120
- ₹130
Correct Answer: c)
Explanation:
Total expenditure = \(8 \times 145 = ₹1,160\).
Men’s total expenditure = \(5 \times 160 = ₹800\).
Women’s total expenditure = \(1160 – 800 = ₹360\).
Average expenditure of women = \(\dfrac{360}{3} = ₹120\).
कुल खर्च = \(8 \times 145 = ₹1,160\)।
पुरुषों का कुल खर्च = \(5 \times 160 = ₹800\)।
महिलाओं का कुल खर्च = \(1160 – 800 = ₹360\)।
महिलाओं का औसत खर्च = \(\dfrac{360}{3} = ₹120\)।
