John and rachel share £2400 prize money at a ratio of 2:4. How much do they each get?

Stels [109]

Answer: John:£800

Rachel:£1600

Step-by-step explanation:

Since John and Rachel shared £2400 in the ratio 2:4, it means that £2400 was equal to(2+4) units, which is 6 units.

Thus, each unit is £2400/6= £400

Hence, John got £400x2=£800, and Rachel got £400x4=1600.

The local pet store surveyed 50 people about pets. Eleven of these people owned dogs, 13 owned cats, and 6 owned fish. One perso

siniylev [52]

Answer: 29

Step-by-step explanation:

Let S denotes the total number of people surveyed, A denotes the event of having dog , B denotes the event of having cats and C denotes the event of having fish.

Given : n(S)=50 ;n(A)=11 ; n(B) =13 and n(C)=6

Also, n(A∩B)=5 ; n(A∩C) = 2 and n(B∩C)=3 and n(A∩B∩C)=1

We know that,

$n(A\cup B\cup C)=n(A)+n(B)+n(C)-n(A \cap B)-n(A \cap C)-n(B \cap C)-n(A \cap B\cap C)\\\\=11+13+6-5-2-3+1=21$

Now, the number of people owned none of these pets :-

$n(S)-n(A\cup B\cup C)\\\\=50-21=29$

Hence, the number of people owned none of these pets =29
