Number of mangoes = 250
So the rotten mangoes = 12% of 250
We can write it as
= 250 × 12/100
= 30
Remaining mangoes = 250 – 30 = 220
We know that
Mangoes crushed = 10% of 220
We can write it as
= 220 × 10/100
= 22
So the balance number of mangoes = 220 – 22 = 198
Therefore, 198 mangoes were in good condition
