Question

A football team won 65% of the total matches they played during the year. If they lost 21 matches in all and no matches were drawn, find the number of matches played during the year.​

Answer 1

Step-by-step explanation:

find the amount and the compound interest - principal $7000 ;rate p.c.p.a 10; duration year 4Principal =7000, R =4%, n =2        (∵ semiannually compounded),

t =3 years

Using the formula, we have

A=P(1+100R)n.t

⇒A=7000(1+1004)2×3

⇒A =7000×(1.04)6

⇒A =7000×1.26531902

Amount =8857.23

Compound interest = Amount − Principal

=8857.23−7000

Compound interest =1857.23 Rs.

Answer 2

Answer: The total matches played by a Team  are 60 Matches.

Step-by-step explanation: Let the Total Matches Played = x

The  Percentage of Lost Matches are = 100% - 65% = 35%

The Number of Matches Played during the Year = $\frac{x*35}{100}$ = 21

35x = 21*100; x = $\frac{21*100}{35}$; x = 3*20; x = 60
