Show Hint
- 854
- 848
- 798
- 782
The Correct Option is A
Solution and Explanation
Number of boys last year \( = 610\).
The number decreased by \(20\%\) this year, so boys this year \( = 610 \times (1 - 0.20) = 610 \times 0.8 = 488\).
Step 2: Find the number of girls using the given percentage of boys.
Girls \( = 175\%\) of boys this year \( = 1.75 \times 488\).
\(1.75 \times 488 = 854\).
Final Answer:
The number of girls in the school is 854, so option A is correct. \[ \boxed{854} \]
