B Correct answer
Explanation

Total spent by 9 people = 9 * 175 = 1575. Total spent by 5 boys = 5 * 150 = 750. Total spent by 4 girls = 1575 - 750 = 825. Average for girls = 825 / 4 = 206.25.

AI explanation

The total amount spent by all 9 people is 9 multiplied by 175, which equals Rs. 1575. The total amount spent by the 5 boys is 5 multiplied by 150, giving Rs. 750. The total amount spent by the 4 girls is 1575 minus 750, yielding Rs. 825. The average amount spent by the girls is 825 divided by 4, which equals 206.25.
