94. A tin of peas & carrots and two mangoes weighing 300 grams each are placed on one side of a scale. To balance the scale, 4 tins of condensed milk each weighing 250g are
placed on the other side. Determine the mass of the peas & carrots.

  400 g

Step-by-step explanation:

Let p represent the mass of the peas & carrots. The scale is balanced when the mass on one side is equal to the mass on the other side.

  p + 2(300 g) = 4(250 g)

  p = 1000 g -600 g . . . . . subtract 600 g

  p = 400 g

The mass of the peas & carrots is 400 grams.
