❍Let's consider the ages of Sachin and Amit be 7x and 4x respectively.

• As per given in the question the ratio of the ages of Sachin and Amit is 7:4 and the sum of their ages is 33 years and we are said to find the ratio of their ages before 6years.

$\: \: \: \\ \: \: \: \sf \: : \implies \: 7x + 4x = 33 \\ \\ \\ \: \: \: \sf \: : \implies \: 11x = 33 \\ \\ \\ \: \: \: \sf \: : \implies \: x = \cancel \frac{33}{11} \\ \\ \\ \: \: \: \sf \: : \implies \: x = 3$

$\large{\mathfrak{\underline{Substitute\:the\:values}}}$

$\sf \: the \: age \: of \: sachin = 7x \\ \\ \: \: \sf \: = 7 \times 3 \\ \\ \: \: \sf \: = 21 years \\ \\ \: \: \sf \: the \: age \: of \: amit = 4x \\ \\ \: \: \sf \: = 4 \times 3 \\ \\ \: \: \sf \: = 12 \: years$

$\: \: \: \\ \: \:$

Before 6 years their ages will be

21 - 6 = 15years and 12 - 6 = 6years.

$\: \: \sf \therefore \: ratio = \frac{15}{6} = \frac{5}{2} = 5 \ratio2$
