Answer 1

Total money he spend is Rs.760
He sold the new variety for Rs.855
profit =SP>CP
855-760=95
Profit percent= 95/760×100= 12.5%

Answer 2

Hey


Solution :-


CP of rice =


Rs ( 20 * 18 )


= Rs 360


Now ,

CP of rice =


Rs ( 25 * 16 )

= Rs 400



Total CP

= Rs ( 360 + 400 )


= Rs 760


Now ,


SP of rice =

Rs ( 19 * 45 )


= Rs 855


Gain

= SP - CP


= Rs ( 855 - 760 )


= Rs 95


Gain %


= Gain / CP * 100 %


= 95 / 760 * 100 %


= 5 / 40 * 100 %


= 100 / 8 %


= 25 / 2 %


= 12 . 5 %
