72 :

*28*72 - 28 = 44

44% --> 220

1% --> 220 ÷ 44 = 5

72% --> 72 x 5 = 360 male spectators

**25 + 28 = 53**53% --> 53 x 5 = 265

**Before**

100 - 37.5 = 62.5

62.5% --> 265

**After (number the same, percentage has gone up)**

37.5% --> 37.5/62.5 x 265 = 159 male spectators

360 - 159 = 201 male spectators

201 male spectators must leave the stadium.

20 % of people are performers....

ReplyDeleteDoes it include male and female?

Why 25 + 28?

There is a big fruit tree in a garden. It bears fruits at a constant rate everyday. Paul will pick the fruits and sell. Animals will pluck and eat the fruits. 25 men can pick all the fruits in 15 days and 66 animals can eat all the fruits in 10 days. If 1 man can pick twice the number of fruits as 1 animal, find the number of days it take for 10 men to pick and 10 animals to eat all the fruits together.

ReplyDeleteIs the answer 40 days?

ReplyDeleteWhere did you get the question from?

What level (Secondary?) is it for?
