A) 1200
B) 800
C) 1000
D) Cannot be determined
Correct Answer: A
Solution :
Let the number of boys and girls be \[4x\] and \[6x\]respectively. According to question, \[\frac{4x+200}{6x}=\frac{5}{6}\] \[\Rightarrow \] \[5x=4x+200\] \[\Rightarrow \] \[x=200\] Therefore, number of girls\[=6x\] \[=6\times 200=1200\] Short-Trick Ratio I. Ratio (4 : 6) increasing of boys 200 and ratio increase = 1 II. Ratio (5 : 6) 1 = 200 Hence, 6 = 1200You need to login to perform this action.
