Question

In a standard of a school 55% of the students are boys. If there are 144 girls how many boys are there?

Answer 1

Answer:

176

Step-by-step explanation:

144=$\frac{45}{100}$×x
   x=144×$\frac{100}{45}$
   x=$\frac{14400}{45}$
   x=320

so as there are 320 students in the class ,we can now easily find the boys percentage
boys % = $\frac{55}{100}$×320
            = 0.55×320
             =176


                                                           or

no. of boys = total students - no. of girls
                  = 320-144
                  = 176
