Of 140 mangoes in a basket 42 of them were bad what percentage of the mangoes was good

Calculating the percentage of good mangoes:

Good mangoes = 140 - 42
Good mangoes = 98

Percentage of good mangoes = (98 / 140) * 100
Percentage of good mangoes = 0.7 * 100
Percentage of good mangoes = 70%

Therefore, 70% of the mangoes in the basket were good.
