Question

A boy saves ₹$1.20$ daily. In how many days will he be able to save an exact number of rupees?

• A. $2$
• B. $3$
• C. $5$
• D. $6$

Answer 1

The correct option is C

$5$

In this question, we will find the multiples of $1.20$.

$$\begin{gathered} 1.20\times 1=1.20 \\ 1.20\times 2=2.40 \\ 1.20\times 3=3.60 \\ 1.20\times 4=4.80 \\ 1.20\times 5=6 \\ 1.20\times 6=7.20 \end{gathered}$$

Therefore, we can see here that at the $5^{th}$day, the boy will be able to save an exact number of rupees.

Hence, option C is correct.
