उत्तर
In first balance-
1 Mango + 1 orange = 3 orange
Therefore, 1 mango = 3 orange – 1 orange
= 2 orange
In second balance,
2 papaya = 2 orange + 1 mango
= 2 orange + 2 orange (Because 1 mango = 2 orange)
= 4 orange
Therefore, 1 papaya = 2
orange In third balance,
1 papaya + 1 mango = 2 orange + 2 orange (Because 1 papaya = 2 orange and 1 mango = 2 orange)
= 4 orange.
Hence, 4 oranges will balance the one papaya and together with one mango in third balance.
