What number must be subtracted from \[1,02,59756\] to get \[77,63,835\]?

Hint: Here we have two numbers and we are asked to find the number that subtracts the first number to give the second number. Hence we have to assume an arbitrary number x that subtracts the first number to give the second number. We have to use simple subtraction to get the final answer.

Complete step-by-step solution:
 The first number is \[1,02,59756\]
The arbitrary number is X
The resultant number is \[77,63,835\]
According to the question we have:
First number – X = Resultant number
Therefore we have,
\[1,02,59765 - X = 77,63,835\]
Solving for X we get:
\[X = 1,02,59765 - 77,63,835\]
Hence we get:
\[X = 2495921\]
Hence \[1,02,59756\] when subtracted by \[24,95,921\] gives \[77,63,835\].
Additional Information: Whenever two numbers are given and ask you to find another number it is always recommended to use an arbitrary number to solve the given question. Here we substitute X according to the question and hence receive the answer. It is very important to understand the question and take the assumption accordingly. One should be well versed with the basic arithmetic operations i.e. addition, subtraction, multiplication, and division.

Note: One should be clear with subtraction and should not commit any mistake while solving X. Whenever there is a big number it is suggested to solve the problem slowly and carefully so that one doesn’t commit silly mistakes. With the understanding of simple arithmetic operations, one can easily solve the problems. Addition, subtraction, multiplication, and division are the 4 basic arithmetic operations that give us an idea to solve this kind of problem.
