Given:
Cost of 2 kg apples + 2 kg grapes = ₹160
Cost of 4 kg apples + 3 kg grapes = ₹300
Let:
Cost of 1 kg apple = ₹x
Cost of 1 kg grape = ₹y
Solution:
2x + 2y = 160 ______(Equation 1)
4x + 3y = 300 ______(Equation 2)
x + y = 80
y = 80 – x__________(Equation 3)
4x + 3(80 - x) = 300
4x + 240 - 3x = 300
x + 240 = 300
x = 60
