in a week mr afzal filled 10litres of petrol at rs 34.90 and 12 litres of petrol at 31.85 from two different petrol pumps. how much did he spend in all on petrol that week?​

Answer 1

$\underline { \pink { In \: First \: petrol \:pump :}}$

$Number \: of \: litres \:of \: petrol \: filled =10$

$Cost \: of \:1 \: litre \: petrol = Rs \: 34.90$

$\blue{ Total \: cost } = 10 \times 34.90 \\= Rs \:349\: --(1)$

$\underline { \pink { In \: Second \: petrol \:pump :}}$

$Number \: of \: litres \:of \: petrol \: filled =12$

$Cost \: of \:1 \: litre \: petrol = Rs \: 31.85$

$\blue{ Total \: cost } = 12 \times 31.85 \\= Rs \:382.20\: --(2)$

$\red{ Total \: amount \: spent \: for \: petrol } \\\red{ by \: Afzal \: in \:a \: week } \\= (1) + (2) \\= Rs \: 349 + Rs \: 382.20 \\= Rs \:731.20$

Therefore.,

$\red{ Amount \:spent \: by \:Afzal } \green {= Rs \:731.20}$
