• D. $RS.15.37$

Answer 1

The correct option is B $Rs.16.47$

We know that 100 paise is 1 Rupee.

So $5$ Paise $=0.05$ Rupees

Also $40$ Paise $=0.4$ Rupees

Now Three Rupees $5$ Paise $=3$ Rupees $+0.05$ Rupees $=3.05$ Rupees

Also Five Rupees $40$ Paise $=5$ Rupees $+0.40$ Rupees $=5.40$ Rupees

Now to find (Three rupees $5$ paise)$\times$(five rupees $40$ paise)

$=3.05\times 5.40$

$=Rs.16.47$
