Question

in a school 4by5 of children are boys. if the number of girl is 200, find the number of boys. STEP BY STEP ANSWER​

Answer 1

Answer:

800

Step-by-step explanation:

number of children= x

number of boys = 4/5 of number of children

= 4/5×x = 4x/5

number of girls = 200

number of girls = number of children- number of boys

= x - 4x/5

= x(1-4/5) ( x is taken common)

= x( 5/5-4/5)

= x(1/5)

= x/5

according to the statement :-

x/5 = 200

= x = 200×5

= x= 1000

thus number of boys= 4x/5

= 4× 1000/5

= 4× 200

= 800
