Answers
Answer:
Boys =18
Girls=36
Step-by-step explanation:
Let Total no of students be =x
No of girls =2/3×x
No of boys =1/3×x
x=54
No of boys is 1/3×54=18
No of girls is 2/3×54=36
Number of boys = 1/3
Means the number of girls = 2/3
___________ [ GIVEN ]
• We have to find the number of girls.
_____________________________
• Let total number of students be M.
» In a class the number of boys is 1/3 of the total number of students which is 54.
Number of boys = 1/3 M
Number of girls = 2/3 M
Also we have given total number of students = 54
A.T.Q.
→ × 54 = M
→ M = 18
Number of girls = × 54 = M
= 36
______________________________
Number of boys = 18
Number of girls = 36
________ [ ANSWER ]
______________________________
✡ Verification :
Total number of students = Number of boys + Number of girls.
54 = Number of boys + Number of girls.
From above calculations we have number of boys = 18 and number of girls = 36
=> 54 = 18 + 36
=> 54 = 54
