Here, the question has asked us to find the x. To find x we will follow the method of product of means and product of extreme. Then we will get the answer.

ANSWER:-

✓ Value of x is 45.

GIVEN:-

» 12:x :: 20:75

TO FIND:-

➲ Value of x in 12:x :: 20:75

FORMULA:-

✧ Value of x = (Product of mean = Product of extreme)

SOLUTION:-

$\maltese \: \: \underbrace{\sf a\ :\underbrace{ b\ ::\ c}\ : d}$

$\maltese \: \: \underbrace{\sf 12\ :\underbrace{\sf x\ ::\ 20}\ : 75}$

$\maltese \: \:{\sf {\underbrace{\sf x\ ::\ 20}} = Product \: of \: means}$

$\maltese \: \: {\sf { \underbrace{12 \ :\ 75}} = Product \: of \: extreme}$

$\dag \: { \sf{20 \times x = 12 \times 75}}$

$\dag \: { \sf{20x =900}}$

$\dag \: { \sf{x =900 \div 20}}$

$\dag \: { \sf{x =900 \div 20 = 45}}$

$\dag \: { \sf{x = 45}}$
