P = 4587946, Q = 5432322, R = 4595566. Find the value of P + Q − R.
P + Q  R = 4587946 + 5432322  4595566 = 5424702
A + B + 45896 = C + D. lf C + D = 96023 + B, find the value of A.
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
You have to replace the digit 8 in the numbers 5487952 and 798556 such that their sum becomes 6231508. By which one of the following digits would you like to replace 8?
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.
What is the difference between the place value of 2 and 4 in the number 23457.
Place value of 2 is 20,000
Place value of 4 is 400
Therefore, the difference between 20000 & 400 is 19600
What greatest number should be subtracted from 2546987 such that the difference becomes divisible by 3?
If you find the difference between 2546987 and 2546984 it would be 3 which is directly divisible by 3.
If + equals to  and  equals to + then find the value of 19 + 17 − 75 + (8 − 4).
Let's first change the questions as per the conditions
1917+75(8+4)
According to Bodmas
First solve the bracket.
1917+75(12)
2+7512
7712 = 65
If x = 956, y = 877and x − y = z. Find the value of x + y + z.
x  y = z
956  877 = 79 = z
therefore,
x +y +z = 956+877+79 = 2603
A = 564454, B = 8787411, C = 8784515. Find the value of 2(A + B − C).
A= 564454
B= 878411
C= 8784515
2(A+BC)
2(564454+ 878411 8784515)
= 2(7341650)
= 14683300
Which one of the following numbers should be added to 4456454 such that their sum becomes equal to the difference of 49565565 and 2479564?
Difference of 49565565 and 2479564 = 49565565  2479564 = 47086001
Required number = 47086001 4456454 = 42629547
X and Y are two natural numbers. X is 5646 more than Y. If sum of X and Y is 545498, find the value of 3X + Y
Answer is 1096642
3 x + y so 3 × 545498 = 1636494
x is 5646 more than y
So, 545498  5646 = 539852
Hence, 1636494  539852 = 1096642
