**Assertion**

# Mr Baja has enough money to buy $12$ magazines. If the cost of a magazine and a pair of trousers is in the ratio $4:16$, then $4$ pair of trousers he can buy with the same amount of money.

**Reason**

# When $x$ is added to both the terms of the ratio $3:4$, it becomes $8:9$, then the value of $x$ is $5$
