Question

in a school out of 300 students 70% are girls and 30% are boys if 30 girls leave and no new boy is admitted what is the percentage of girls in the school ​

Answer 1

Step-by-step explanation:

Total students = 300

girls = 300 *70%

= 300*70/100

= 210

boys = 300*30%

= 300*30/100

= 90

30 लड़कियों के विद्यालय छोड़कर जाने पर अब शेष

कुल विद्यार्थी = 270

लड़कियाँ = 180/270 * 100

= 2/3 * 100

= 200/3 = 66.67%

Answer 2

Answer:

Total percentage of girls=70%

70/100×300=210girls

girls leave=30

remaining girls=210-30=180girls

remaining students=300-30=270

%age of girls=180/270×100=200/3=66.66%ans.
