Question 54

If mathematical operators `$$-$$' and `$$\div$$' are interchanged, then the value of
$$15 \times 4 + 15 - 11 \times 33 \div 98$$ is

Solution

$$15 \times 4 + 15 - 11 \times 33 \div 98$$

After interchanging the sign $$-$$' and `$$\div$$

$$15 \times 4 + 15\div11 \times 33-98$$

$$15\times\ 4+\frac{15}{11}\times\ 33-98$$

$$60+45-98$$
