Given:

Find the difference between 3/4 of Rs. 70 and 3/4percent of Rs. 70​?

To find:

The difference

Solution:

3/4 of Rs.70:

$\frac{3}{4} \times 70$

= $Rs. \:\frac{210}{4}$

3/4 percent of Rs. 70​:

$\frac{\frac{3}{4} }{100} \times 70$

= $\frac{3}{4} \times \frac{1}{100} \times 70$

= $\frac{3}{4} \times \frac{1}{10} \times 7$

= $\frac{3}{4} \times \frac{1}{10} \times 7$

= $Rs.\:\frac{21}{40}$

The difference between 3/4 of Rs.70 and 3/4 percent of Rs. 70​:

$\frac{210}{4} - \frac{21}{40}$

taking the L.C.M. of the denominators 4, 40 which is 40

= $\frac{2100 \:-\:21}{40}$

= $\frac{2079}{40}$

= $\bold{51.975}$

Thus, the difference between 3/4 of Rs. 70 and 3/4 percent of Rs. 70​ is → Rs. 51.975.
