Question 41

If $$'\times'$$ stands for 'addition', $$'\div'$$ stands for 'subtraction', $$'+'$$ stands for 'multiplication'
and $$'-'$$ stands for 'division', then
$$75 \times 345 + 15 - 23 \div \left(15 + 18\right)$$ = ?

Solution

Given Equation,

$$75 \times 345 + 15 - 23 \div \left(15 + 18\right)$$ = ?

As per conditions given in question,

We get,

$$75+345\times\ 15\div\ 23-\left(15\times\ 18\right)=?$$

Lets solve this using the rule of BODMAS

$$75+345\times\ 15\div\ 23-270=?$$

$$75+345\times\frac{15}{23}-270=?$$

$$75+225-270=?$$

$$75+225-270=30$$

Hence, Option D is correct.
