Answer 1

Answer: (C)

1.92$Pagybrought$5$purpletomatosfor$\$1.20$

Cost of $1$ purple tomato will be $=$ $\frac{1.20}{5}=0.24$
Pagy brought $6$ green tomato for $\$1.80$
Cost of $1$ green tomato will be $=$ $\frac{1.80}{6}=0.30$
So cost of $3$ purple tomato and $4$ green tomato will be
$\Rightarrow 0.24\times 3+0.30\times 4$
$\Rightarrow 0.72+1.2$
$\Rightarrow 1.92$
Cost of tomatoes on the chair is $\$1.92$.
