Question

In a class of 60 students 60 percent are girls how many more girls needed ti make it 70 percent

Answer 1

10 girls need to make 70%percent

Answer 2

Answer:

Present percentage of girls = 60%

Percentage of girls needed = 70%

More percentage of girls needed = 70% - 60% = 10%

More number of girls needed to make 70% = $\frac{10}{100}$ × 60

                                                                         = $\frac{1}{10}$ × 60

                                                                          = 6

So 6 more girls are needed to make it 70%.
