Test:Addition & Subtraction - 3 - CTET & State TET MCQ

P + Q - R = 4587946 + 5432322 - 4595566 = 5424702

Place value of 2 is 20,000
Place value of 4 is 400
Therefore, the difference between 20000 & 400 is 19600

x - y = z
956 - 877 = 79 = z
therefore,
x +y +z = 956+877+79 = 2603

Let's first change the questions as per the conditions

19-17+75-(8+4)

According to Bodmas

First solve the bracket.

19-17+75-(12)

2+75-12

77-12 = 65

We need to replace 8 by some digit to get Sum 6231508
6286508 - 6231508 = 55000
=> Sum would be reduced by 55000 Currently Values of 8 are 80000  & 8000
=> 88000 - 55000 = 33000 = 30000 + 3000
Hence 8 should be replaced by 3.

Difference of 49565565 and 2479564 = 49565565 - 2479564 = 47086001

Required number = 47086001- 4456454 = 42629547

It is given that C + D = A + B + 45896
According to the question
45896 + A + B = 96023 + B
45896 + A = 96023 + B - B
A = 50127

A = 564454 B = 8787411 C = 8784515

Now, calculate 2(A + B - C):

2(A + B - C) = 2(564454 + 8787411 - 8784515)

Now, perform the calculations within the parentheses:

= 2(564454 + 2896)

Now, add the values inside the parentheses:

= 2(567350)

Finally, multiply by 2:

= 1134700

So, the value of 2(A + B - C) is 1134700

If you find the difference between 2546987 and 2546984 it would be 3 which is directly divisible by 3.

Total passengers on the train = Initial passengers - Passengers who got off + Passengers who got in

Let's plug in the given values:

Total passengers on the train = 5484 - 576 + 463

Now, let's calculate:

Total passengers on the train = 5484 - 576 + 463 = 5371

Let's denote the unknown number as x.

The sum of 54998 and 547898 is 54998+547898=602896

The given condition is that when x is added to this sum, the resulting number is 6699 more than 495588502:

602896+x=495588502+6699

Now, let's solve for x:

x=(495588502+6699)−602896

x=495595201−602896

x=494992305

A - B = 576
A - B + C = 5556
So, 576 + C = 5556
C = 5556 - 576 = 4980
C = 3A
A = C/3 = 4980/3 = 1660
So, A - B = 576
1660 - B = 576
B = 1660 - 576
B = 1084

A=3B
B=2C
C=4D
D=54546
therefore, C= 4 * 54546= 218184
B= 218184 * 2 = 436368
A= 3 * 436368 = 1309104
therefore, (A+B+C+D) = 2018202                                      

difference is = 346565
first number = 935974
second number be = X
according to the question
935974 - x= 346565
X= 935974-  346565
X= 589409
now the sum of both numbers is= 935974+589409
= 1525383
