Question

Avanti's present age is $\mathrm{y}\mathrm{years}$ and her mother's age is $4$years less than $3$times her age, then her mother's present age is

• A. $(3\mathrm{y}+4)\mathrm{years}$
• B. $(4\mathrm{y}-3)\mathrm{years}$
• C. $(3\mathrm{y}-4)\mathrm{years}$
• D. $3(\mathrm{y}-4)\mathrm{years}$

Answer 1

The correct option is C

$(3\mathrm{y}-4)\mathrm{years}$

Given;

The present age of Avanti is $\mathrm{y}\mathrm{years}$.
now, three times of Avanti age will be $3\mathrm{y}\mathrm{years}$

According to question,

Avanti's mother's age is $4\mathrm{years}$ less than $3$ times her age,

so her mother's age is $(3\mathrm{y}-4)\mathrm{years}$.
Hence, the correct option is C.
