Question

how to solve this problems​

Answer 1

Answer:

(1) Let x be the number of winners.

Then the number of participants who do not win is given as (63 - x)

The prize money given to x winners = Rs

(100x)

The prize money given to (63 - x) participants is = Rs 25(63 - x)

According to the given data, the total prize money distributed = Rs 3000

Therefore, 100x + 25(63 − x) = 3000

4x + (63x) = 120

3x + 63 = 120

x = 19x = 19

Therefore, the number of winners is 19.p explanation:

2.4BOYS 15 GIRLS

Answer 2

Answer:

Let number of winners be x

So number of losers be 100 - x

According to statement

5000x + 750×(100 - x) = 1,60,000

5000x + 75000 - 750x = 1, 60, 000

4250x = 1, 60, 000 - 75000

4250x = 85000

x = 20

So number of winners = 20 and number of losers = 80.

Let number of boys be y

so number of girls = 3y

y + 3y = 20

4y = 20

y = 5

So number of boys = 5 and number of girls = 15.
