Instructions

What approximate value should come in place of the question mark (?) in the following questions ? (Note: you are not expected to calculate the

exact value)

Question 114

$$170\times14\div181=?$$

Solution

Here, the options are quite far from each other and decimal accuracy is not important,

We can approximate 181~180

And now solving by reframing (17*14)/18 =(17/18)*14

It is evident that answer will be slightly less than 14 and hence correct option is 13.
