Answers
Total number of girls in collages D and E together are approximately what percentage of total number of girls in colleges A , B and V together ?
solution : no of girls in college A = 450
no of girls in college B = 550
no of girls in college C = 475
no of girls in college D = 500
no of girls in college E = 550
so total number of girls in colleges D and E together = 500 + 550 = 1050
total number of girls in collages A, B and C together = 450 + 550 + 475 = 1375
now let x % of total number of girls in colleges D and E together = total number of girls in collages A, B and C together
⇒x/100 × 1050 = 1375
⇒x = 137500/1050 = 13750/105 = 130.95 ≈ 131
Therefore approximately 131% of total number of girls in colleges D and E together is equal to total number of girls in collages A, B and C together
Answer:
