Answer 1

Given:

Karl, Serene and Pauline have 1281 stickers altogether. Pailine had 3 times as many as Serene. Karl had 175 stickers fewer than Pauline.

Required:

We need to find that how many stickers Pauline have

Step-by-step explanation:

First consider Karl as K, Serene as S and Paulie as P

so

`K+S+P=1281`

now also

`\begin{gathered} P=3S\Rightarrow(P)/(3)=S \\ and\text{ } \\ K=P-175 \end{gathered}`

Put S and K in 1st equation

`\begin{gathered} P-175+(P)/(3)+P=1281 \\ \\ 3P-525+P+3P=3843 \\ P=624 \end{gathered}`

By P

`\begin{gathered} S=(P)/(3)=(624)/(3)=208 \\ \\ and \\ K=P-175=449 \end{gathered}`

Final answer:

Pauline has 624 stickers
