Solution:
73 – 27
= 73 + 99 – 27 – 99
= 73 + 99 – 27 – 100 + 1
= 73 + (99 – 27) - 100 + 1
= 73 + 72 - 100 + 1
= (73 + 72) – 100 + 1
= 145 - 100 + 1

= 46
Therefore, 73 – 27 = 46

To find:-
Find the number of rupees 5 coins.
Solution:-
Let the number of rupees 2 =X
Let the number of rupees 5=Y
Case-1:-
total number of coins=80
=>X+Y=80--------(1)
Multiplying (1) with 2
=>2X+2Y=160-----(2)
Case-2:-
The total amount in her purse=Rs. 232
=>2X+5Y=232-----(3)
we have pair of linear equations in two variables
On Using elemination method
2X+5Y=232
2X+2Y=160
(-)
-------------------
0+3Y=72
-------------------
=>3Y=72
=>Y=72/3
=>Y=24
Answer:-
The number of rupees 5 coins =24
