Question

In the ratio 7 : 8, if the consequent is 40, what is the antecedent?

Answer 1

In a ratio a : b, 'a' is known as the antecedent and 'b' is known as the consequent.
In the given ratio, let the antecedent be 7x and the consequent be 8x, respectively,
But consequent = 8x = 40
x = $\frac{40}{8}$ = 5
Therefore, the antecedent = 7x = 7$\times$5 = 35.
