Question 121

$$8\frac{1}{4} + 60\% of \frac{6}{5} = 15 - ?$$

Solution

Expression : $$8\frac{1}{4} + 60\% of \frac{6}{5} = 15 - ?$$

=> $$15 - ? = \frac{33}{4} + (\frac{60}{100} \times \frac{6}{5})$$

=> $$15 - ? = \frac{33}{4} + \frac{18}{25}$$

=> $$? = 15 - \frac{33}{4} - \frac{18}{25}$$

=> $$? = \frac{27}{4} - \frac{18}{25}$$

=> $$? = \frac{675 - 72}{100} = 6.03$$
