**In this post we will discuss few important types of Ratio and Proportion Questions that are asked in IBPS PO and SSC CGL exam and solve them using smart method**

Ratio and Proportion questions are asked in IBPS PO and SSC CGL Exam directly or indirectly. Knowing tricks to
solve Ratio and Proportions questions is mandatory, as this will help you to
save a lot of time during your examination.

In the previous post, Ratio and Proportion 1- Ratio and
Proportion Formulas for IBPS PO and SSC CGL Exams, we have discussed the concept of Ratio and Proportion and few basic Ratio and Proportion Questions
that are asked in IBPS PO and SSC CGL Exams. In this post we will
discuss two more types of Ratio and Proportion Questions that are
frequently asked. We will then solve them using smart method which will help you
to save time.

In this module, Ratio and Proportion Questions are discussed where you have to Calculate the total amount, based on the given Ratio and Proportion difference. These ratio and proportion question can be solved using Ratio and Proportion Formulas

**Example:**

**Question:**A sum of money is divided among A, B, C, D in the ratio 3:5:8:9 respectively. If the share of D is Rs.1872 more than the share A, then what is the total amount of B and C?

**Solution:**

**Step 1:**

A:B:C:D = 3:5:8:9 (This means when that when the whole
part will be divided, A will get 3 parts, B will get 5 parts, C will get 8 parts
and D will get 9 parts)

**Step 2:**

As it is given in the question that D is 1872 Rupees more
than A

We can say that,

D - A = 1872

9x - 3x = 1872

6x= 1872

**Step 3:**

we need to find the total amount of money for B and C

B + C = ?

5x + 8x = ?

13x = ?

**Step 4:**

As we have like terms, with the concept of equivalent
proportionality, we cross multiply-

B + C = (13 x 1872) / 6 ( the x gets cancelled, as it is
common)

B + C = 4056

**Module 4:**

In this module, Ratio and Proportion Questions discussed are on change of ratio when there is a change in the absolute value.

**Example:**

**Question:**Amit, Sumit and Vinit divide an amount of Rs.2800 among themselves in the ratio of 5:6:3 respectively. If an amount of Rs.200 is added to each of their shares, what will the new ratio of their new shares.

**Regular Method**

**Solution:**

**Step 1:**

From the given information we know that,

5x + 6x + 3x = 2800 (x here indicates single part)

14x = 2800

x = 2800/14 = 200

**Step 2:**

Individual amount for

Amit: 5 x 200 = 1000

Sumit: 6 x 200 = 1200

Vinit: 3 x 200 = 600

**Step 3:**

As it is said that 200 rupees is added to each share-

Amit: 1000 + 200 = 1200

Sumit: 1200 + 200 = 1400

Vinit: 600 + 200 = 800

**Step 4:**

Now the new share of Amit, Sumit and Vinit is

Amit : Sumit : Vinit :: 1200 : 1400 : 800

**Step 5:**

By simplification,

The ratio of Amit : Sumit : Vinit = 6:7:4

**Smart Method**

**Solution:**

**Step 1:**

As we know that 14x = 2800 (by adding up all the
parts)

x = 2800

**Step 2:**

In the question it is said that, the share increased by
Rs.200, this means that ratio is increased by one part, So by that we can get new
ratio of Amit:Sumit:Vinit as

5 + 1 : 6 + 1 : 3 + 1 = 6:7:4

Therefore, The new ratio of Amit:Sumit:Vinit is 6:7:4.
