Answer: x=60 Step-by-step explanation: Let number of boys =x ⟹ number of girls D=150−x given that , (150−x) is x% of total(150) 150−x= x/100 ×150 150−x= 3x/2 5x/2=150 x=60 Reply
Number of boys = x Number of girls = (150 – x) According to the question, ⇒150×x100=(150−x)⇒150×x100=(150−x) ⇒3x=300−2x⇒3x=300−2x ⇒5x=300⇒5x=300 ⇒x=60 so,answer is 60 Reply
Answer:
x=60
Step-by-step explanation:
Let number of boys =x
⟹ number of girls D=150−x
given that , (150−x) is x% of total(150)
150−x= x/100 ×150
150−x= 3x/2
5x/2=150
x=60
Number of boys = x
Number of girls = (150 – x)
According to the question,
⇒150×x100=(150−x)⇒150×x100=(150−x)
⇒3x=300−2x⇒3x=300−2x
⇒5x=300⇒5x=300
⇒x=60
so,answer is 60
