$\rule{200}{2}$

$\Large{\sf{Given :}}$

Cost of 15 litres oil = 750 Rs.

$\rule{200}{2}$

$\LARGE{\sf{Solution :}}$

Cost of 15 liters oil = 750 Rs.

Then,

Therefore ,

$\hookrightarrow \sf10 \: litres \: oil \: cost = 50 \times 10 \\ \\ \hookrightarrow \sf 10 \: litres \: oil \: cost = 500 \: \:$

Hence , the required value is ₹ 500
