Dear Reader, **IBPS PO** exams are starting very soon! (In 5 months tentatively). Below tutorial will help you for sure.

You already know **simplification** is an important topic for bank exams. In this post, you will find two types of problems asked in previous year PO exam.

**Example For Type 1:**

Find the number in place of the question mark:

**? / 676.03 = 1295.6 / ?**

Solution:

We can approximate 676.03 as 676 and 1295.6 as 1296. Therefore, the given equation can be simplified as:

?^{2} = 1296 x 676

Or ? = square root of (1296 x 676)

= square root of (1296) x square root of (676)

= 36 x 26

= 936

Therefore, the ** answer is 936**.

**Tip:** Remember squares of numbers up to 50 to solve such problems easily.

**Example For Type 2:**

Find the number in place of the question mark:

**? = square root of (0.25 x 0.36) x 1/30**

This type was **surprisingly easy** (in last year exams). Only one thing you have to know to solve such problems is the **correct placement of decimal** point in square roots.

Now let us solve the above problem.

square root of (0.25 x 0.36) x 1/30

= square root of (0.25) x square root of (0.36) x 1/30

= 0.5 x 0.6 x 1/30

= 0.30 x 1/30

= 0.01

Therefore, the ** answer is 0.01**.
