The number of boys are 360 and Total children are 600
Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -
A : B ∷ C : D
AND
A x D = B x C
Product of extremes equal to product of means.
Given is in a school 3/5 pupils are boys and 240 are girls
We can write -
Assume that the total children are [x]. Then, we can write the equation as-
3x/5 + 240 = x
x - 3x/5 = 240
0.4x = 240
x = 600
Number of boys = 3/5 x 600 = 3 x 120 = 360
Total children = 600
Therefore, the number of boys are 360 and Total children are 600
