Types of Simplification:

There are two possible ways to ask a question which is related to simplification. Simplification question will take place in all important competitive exam because we can check the individual analytical thinking through the simplification.

  • Finding the missing number from the calculation will be the First type of simplification. In this type to get solution approximate the given number or we can simplify using the basic operations.
  • The second Method will understand the relation between the numbers and simplify the numbers using the rules of simplification.

Examples with an explanation for Simplification:

1). (10.8×16×12)  + (3.6×56×9.2)   =?

  1. 3941.35
  2. 3966.89
  3. 3928.32
  4. 3649.19
  5. 3645.19
Ans: c
Solution:
Even + Even should be always Even. So the unit digit should be in even.
Note: All numbers should be Even.
2). 12.3% of 203 + 23% of  1110 =?
  1. 270.269
  2. 240.269
  3. 280.269
  4. 290.269
  5. None of these
Ans :c
Solution:
Tricks :      A% of B = B % of A
  1. 3/4
  2. 5/7
  3. 3/7
  4. 4/7
  5. None of these

Ans: b
Solution:

4). 3545 ×14.75 – 2325 ×15.25 =?

  1. 15369.5
  2. 16832.5
  3. 11546.5
  4. 12475.5
  5. None of these

Ans: b
Solution:
1220×15 – 5870 ×0.25 = 16832.5
(15+0.25=15.25; 15-0.25=14.75) (a-b , a+b)
Here,
3545+2325=5870 (x+y)
3545– 2325 =1220 (x-y)

5). 27% of 250 +22% of 920 +21% of 660=?

  1. 419.5
  2. 423.5
  3. 408.5
  4. 415.5
  5. None of these

Ans: c
Solution:
Common percentage method:
(250+920+660) =1830
Here 20% is common;
20% of 1830 =366
Further,
1st part (20+7) = 7% of 250 =17.5
2nd part (20+2) = 2% of 920 =18.4
3rd part (20+1) = 1% 660 = 6.6
366+17.5+18.4+6.6 = 408.5

6). 212 +172 -132 = ?

  1. 412
  2. 512
  3. 561
  4. 461
  5. None of these

Ans: c
Solution:
Method:
212 +(172 -132) = 212 +((17+13)(17-13)) = 441 +(30×4) =561
Note: (A2 – B2) = (a+b) (a-b)

7). (22×28)  +  (38×42) = ?

  1. 2122
  2. 2212
  3. 2132

  1. 59.96
  2. 57.16
  3. 51.86
  4. 59.16
  5. None of these

Ans: D
Solution:
(12.75×4) of (464/4) = 51% of 116 =59.16
Note: If any fractional number end with 5 , we can convert that into whole number by this method.

9). 8.2% of 780 +x= 12.9% of 1310

  1. 107.26
  2. 106.53
  3. 105.03
  4. 103.56
  5. None of these

Ans: c
Solution:
82×78/100 + X =129×131 /100
(130-1)(130+1) /100 – (80+2)(80-2) /100 =X
X=105.03
10). 0.875 of 848  + 0.625 of 624= ?

  1. 1132
  2. 1325
  3. 1236
  4. 1250
  5. None of these

Ans: A
Solution:
87.5% of 848 + 62.5% of 624
(7/8 ×848) +  5/8 ×624 = 742 +390 =1132
Note: 87.5% = (100-12.5)%
                      = (1-1/8) =7/8

Simplification Tricks –
Easiest way to choose simplification questions:

STEP 1: Know about BODMAS Rule. Following are the list of priority given for brackets and signs.
STEP 2: If an expression Contains brackets, the expression within the brackets should be simplified first.
STEP 3: If an expression contains ‘Of’, multiplication, division, addition and subtraction, then of should be performed first then followed by multiplication or division.
Proceeding from left to right, addition and subtraction are carried out in the order in which the sign of addition and subtraction are given.
If expression contains ‘Of’ and Division – always do ‘Of’ and then do division
STEP 4: If expression involves all the four operations,then multiplication and division is carried out first in the order in which they are given from left to right. The same rules are carried out for addition and subtraction

·        6 ¼ % = 0.0625
·        10% = 0.1
·        12 ½ = 0.125
·        16 × (2/3)% = 0.166
·        20 % = 0.2
·        25 % = 0.25
·        33 × (1/3)%= 0.33
·        40 % = 0.4
·        50% = 0.5
·        60% = 0.6
·        66 × (2/3) =0.66
·        75 %= 0.75

·        125 % = 1.25
·        150% = 1.5
·        200 % = 2
·        250 % =2.5
Example 2): 60% of 250 +25% of 600
STEP 1: Know the values of 60% =0.6 and 25 % = 0.25
STEP 2: Now directly multiply 0.6×250 + 0.25×600
STEP 3:0.6×250= 150
            0.25×600=150
STEP 4: 150+ 150 = 300
STEP 5:Hence the answer for above series is300
 
Example 3): Solve mixed fraction – Multiplication
EXAMPLE 3: 2×(3/5) × 8×(1/3) + 7 ½ × 2×(2/3)
STEP 1:2×(3/5) × 8×(1/3) = (13/5) × (25/3) = 65/3
STEP 2:  + 7 ½ ×2×(2/3)= 43/6 × 12/5 = 86/5
STEP 3:65/3 + 86/5 = 38×(15/13)
STEP 4:hence the answer for above series is38×(15/13)
Example 4): Solve Mixed Fraction addition
Example 4:19×(3/5) + 23×(2/3) – 24×(1/5)
STEP 1:Take all the whole number outside the bracket i.e. 19+23 -24 = 18
STEP 2:Add fractions within bracket 18×[(3/5) + (2/3) – (1/5)] = 18(16/15)
STEP 3:  Hence the answer for above series is18(16/15)
 
Example 5): (?)2+18×12= 62×5×2
STEP 1:Multiply 18 × 12 = 216
STEP 2:Square of 6 = 36
STEP 3:Multiply 36 ×5×2= 360
STEP 4:(X)+216 = 360
STEP 5:(X)2  = 360-216 = 144
STEP 6:Therefore X = 12
