Answer:
[tex]\huge\mathfrak\blue{Hey\ friend\ your\ answer\ is ..........}[/tex]
Let the cost of Orange toffees be ' ₹ x ' and the cost of Mango toffees be ' ₹ y ' .
Given:
x + y = ₹ 3 ----> eq ①
2x + 5y = ₹ 12 ------> eq ②
Multiply eq ① by 2
= 2x + 2y = ₹ 6
Subtract eq ① from eq ②
2x + 5y = ₹ 12
2x + 2y = ₹ 6
____________
3y = ₹ 6
____________
[tex]=> y = \frac{6 }{ 3 }[/tex]
[tex]{\boxed{=> y = ₹ 2}}[/tex]
Substitute y in eq ①
=> x + 2 = 3
=> x = 3-2
[tex]{\boxed{ => x = ₹ 1 }} [/tex]
( Using Simultaneous equations ........... )
Then we'll get .......
[tex]\huge{\boxed{\boxed{x = 1, y = 2}}}[/tex]
[tex]\huge{\boxed{\boxed {\boxed {Cost\ of\ 3\ mango\ toffees\ = 3 × ₹ 2 = ₹ 6}}}}[/tex]
