Answer 1

Answer:

15kg

Step-by-step explanation:

$cost \: of \: 1 kg \: pulse = 7.50$

$\therefore \:cost \: of \: 18kg \: pulses = 18 \times 7.50 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 135$

Now,

$cost \: of \: 1kg \: rice = 9$

$\therefore rice \: in \: exchange \: of \: pulses = 135 \div 9kg$

$= 15kg$

Therefore, 15kg rice can be bought in exchange for 18kg pulses
