Given:-

=>Which of the following is in proportion?

3,27,9,9

5,11,15,44

3,5,15,25

4,3,36,18

=>to solve the sum we use some general rules of proportion

=>To solve the sum we use FOLLOWING steps as below:-

1)if two ratio are in proportion then first term×fourth term=second term×third term

here first term ×fourth term not equals to second term×third term

here 3×9 not equals to 27×9

=27 not equals to 243

2)here also first term ×fourth term not equals to second term ×third term

here 5×44 not equals to 11×15

=>220 not equals to 165

3)but here first term×fourth term=second term×third term

=>here 3×25=5×15

=>75=75

so 3,5 and 15 ,25 are in proportion

4)here also first term×fourth term not equals to second term×third term

=>here 4×18 not equals to 3×36

=>72 not equals to 108
