Question

If Ram can eat $3$ apples in $4$ minutes. How many apples will he eat in $16$ minutes?

• A. $7$
• B. $10$
• C. $48$
• D. $12$

Answer 1

Answer: (D)

$12$

No. of apples $\left(a\right)$ is directly proportional to the time $\left(t\right)$
$\Rightarrow a\propto t$
$\Rightarrow \frac{a_1}{t_1}=\frac{a_2}{t_2}$

Here, $a_1=3,t_1=4,t_2=16$,

we have to find $a_2$.

$\Rightarrow a_2=\frac{a_1{t}_2}{t_1}=\frac{3\times 16}{4}=12$.
