Question No 5

Jimmy bought 60 Mangoes and 40 Apples. He found 30% of Mangoes and 10%  of apples were overripe. Find the number of fruit in good condition.

Select the correct answer


Solution!
Total fruit = 60 + 40 = 100

=4
Total number of overripe fruit= 18+4=22
Therefore Number of fruit in good condition= 100-22= 78
